Restore Your Original Java Edition Title Text
Disable the Resource Pack
To return to the default Minecraft title screen, open Options → Resource Packs in-game. Locate the Cyrillic Patchwork Blockbench Resource Pack in the active column and move it back to the available list on the left, or remove it entirely.
Reload the Game
Return to the main menu. The standard "Java Edition" text will reappear beneath the Minecraft logo in English, replacing all Russian Cyrillic logos.
Keep the Pack for Later Use
Disabling the pack doesn't delete it from your computer. The resource pack folder remains in .minecraft/resourcepacks/, so you can re-enable it anytime by moving it back to the active column. This is useful if you want to switch between the Russian-themed menu and the original look without reinstalling.
Verify the Change
If the title screen doesn't update immediately after disabling the pack, try closing and reopening Minecraft completely. Resource pack changes sometimes require a full game restart to display properly.
