When Java Edition hangs after you select Play, create a clean official installation with the same game version. If it loads, remove mods, custom resolution, and JVM arguments from the old profile and restore them one at a time. If the Launcher itself is frozen, repair the Launcher through Windows App settings. Back up worlds before Reset or reinstall; never delete.minecraft wholesale.
If the Launcher update or Launcher window is frozen, use the Launcher repair step below. Continue here when the Java game window hangs after Play. A hang while joining a world or server is a different workflow.
2
End only the stalled Minecraft processes
Open Task Manager and end Minecraft Launcher plus the Minecraft or Java process. Reopen only the official Launcher and try once.
3
Create a clean same-version installation
Select Minecraft: Java Edition > Installations > New installation. Name it Loading test, choose the same version as the affected profile, then select Install and launch it.
4
Restore the old profile carefully
If the test reaches the title screen, reset the old profile's custom resolution and JVM arguments and remove its mods. Restore one item at a time and test after each change.
5
Check supported system software
If the clean test also hangs, install available Windows and official graphics-driver updates, close other active programs, and check free storage plus Minecraft's current requirements. Change -Xmx only when the system's RAM and the official memory guide support it.
6
Repair the Launcher branch
If the Launcher itself freezes, run the Xbox app's Gaming Services Repair Tool, then open Windows Settings > Apps > Installed apps > Minecraft Launcher > Advanced options > Repair. Back up worlds before using Reset or reinstalling.
7
Verify repeated loading
Launch the corrected profile twice. Success means it reaches the Java Edition title screen both times. If a clean profile still hangs, keep the version and exact stuck point for Minecraft Support; do not delete .minecraft.
If it does not work
If only one server or world hangs after its loading begins, use that server or world workflow instead of repairing the Launcher.
If the clean profile works, the old profile is the cause; reinstalling the Launcher will not identify which mod or advanced setting failed.
On a PC with 4 GB RAM or less, Minecraft's current guidance may support lowering an altered or newer default -Xmx value to 2 GB after saving the original JVM arguments.
