Do you still have the thread dumps in ~/Library/Logs/Google/AndroidStudio2024.1/ ? If yes, can you please attach them?

Also, do you have any accessibility features enabled? Because I see various calls to java.desktop/sun.lwawt.macosx.CAccessibility flagged for timeouts.

I'm not sure, I just can't get to reach the CAccessibility.accessibilityHitTest method (running under a debugger). But in any case, it doesn't seem like it is causing the freeze, quite the opposite: it's giving up posting the AWT event because the UI is frozen.

All three freeze reports point to similar stacks in the AWT thread:

(corresponding internal crash reports.)

There were two more freeze reports in the attached archive (thanks!) which point to https://youtrack.jetbrains.com/issue/KTIJ-27932/GradleBuildRootsManager.loadLinkedRoot-Slow-Operations-freeze, fixed in 2024.2 (Android Studio Ladybug). You may want to try a canary, and see if things improve.

I've submitted a fix for the stack mentioned in #comment6 that will be available in the next canary build.
