Crash Assistant Mod FAQ

20 questions players actually ask, answered.

How do I open the Crash Assistant screen if I closed it by accident?
The Crash Assistant screen appears automatically the moment Minecraft crashes, so if you closed it you can reopen the same logs from your game directory's crash-reports and logs folders. There is no in-game hotkey to bring the window back after a crash, so grab the files manually or trigger another crash if you still need the upload button.
Does Crash Assistant work if my game freezes or I force-close it instead of crashing?
Crash Assistant only triggers on an actual crash, not on a freeze or a manual force-close, because no crash report is generated in those cases. If your game just hangs, you'll need to find and share the latest.log manually.
Do I need Crash Assistant on my server too?
No, Crash Assistant is client-side only and does nothing on a server. Installing it on the server won't help and won't hurt, but only your own client will show the crash screen and upload logs.
Is it safe to click the upload button? What exactly gets sent?
The upload sends your crash report and game logs to a public log-sharing service and gives you a link anyone can open. Those files can contain your username, file paths, mod list, and sometimes server IPs, so review the link before posting it publicly.
Crash Assistant says it found a problem but the suggested fix doesn't work. What now?
The log analysis only matches common, well-known issues, so it can miss or misidentify unusual crashes. Use the upload button to share the full logs in a support Discord or GitHub issue, where a human can read the actual stack trace.
Why does Crash Assistant say Minecraft is using the wrong GPU?
This usually means your integrated graphics are handling the game instead of your dedicated card, which causes low FPS or graphics-related crashes. The mod detects this and points you toward forcing the correct GPU in your operating system's graphics settings.
Will Crash Assistant itself cause crashes or lag?
Crash Assistant is lightweight and only activates after a crash, so it doesn't affect normal gameplay performance. If you're chasing a crash, it's not the culprit, but you can still test by removing it to rule it out.
Does Crash Assistant work with other mod loaders and modpacks?
It's designed to work alongside other mods and modpacks since it just reads the logs your game already produces. As long as the crash generates a report, Crash Assistant can display and analyze it regardless of what else you have installed.
Can I turn off the automatic crash screen or the analysis?
Yes, Crash Assistant has config options that let you disable the automatic popup or adjust its behavior if you'd rather handle crashes manually. Check the mod's config file in your config folder to toggle these settings.
The upload link expired or won't load for the person helping me. Why?
Log-sharing services often delete uploads after a set time or a certain number of views, so old links stop working. Re-upload the logs and share a fresh link if someone can't open the one you sent.
How do I open the crash assistant screen?
You don't open it manually — the screen appears automatically the next time Minecraft crashes. Just launch the game as normal and wait for a crash to trigger it.
Crash Assistant Mod not showing up after crash
Make sure the mod is actually loaded on the client and that the crash happened during the game rather than before mods loaded. If the game fails so early that the mod never initializes, the screen can't appear.
How do I use Crash Assistant Mod?
After a crash, read the analysis message at the top of the screen, then use the upload button to send your logs and copy the share link. Paste that link wherever you're asking for help.
Does crash assistant work on servers?
No, it's client-side only and does nothing on a server. It only reacts to crashes on your own game instance.
Can I close the crash assistant screen and keep playing?
The screen appears because the game already crashed, so there's nothing left to return to. You can close it, but you'll need to relaunch Minecraft afterward.
Where does crash assistant upload my logs to?
It uploads your logs to a sharing service and gives you a link you can paste into Discord or GitHub. The link is what other people open to read your logs.
Is it safe to upload my logs with crash assistant?
The upload only contains your Minecraft logs and crash reports, which is the same information you'd share manually when asking for help. Review the link before posting it publicly if you're concerned about anything in the logs.
Crash assistant says my gpu is wrong, what do I do?
This means Minecraft is running on an integrated GPU instead of your dedicated one. Change the GPU assignment in your operating system's graphics settings for the Minecraft launcher, then relaunch the game.
Does crash assistant fix the crash for me?
No, it analyzes your logs and suggests a fix, but you still have to apply the change yourself. Treat its message as a diagnosis, not an automatic repair.
Will crash assistant slow down my game?
It stays idle during normal play and only does work when a crash happens, so it shouldn't affect your framerate. Any performance impact comes from other mods, not this one.
