Thanks for report.

Does it hangs consistently or only occasionally?

Studio get deadlocked internally

From attached thread dump:

• "ApplicationImpl pooled thread 2558" have read lock acquired. Waiting on "ApplicationImpl pooled thread 2535" to finish async computation
• "ApplicationImpl pooled thread 2535" could not acquire a read lock because of pending write lock request.

In my experience, it hangs consistently.

Removing beta blocking and reducing priority as a fix has been merged in Hedgehog beta. But keeping this open as a more proper solution is needed

Thanks for the quick fix, Jerome!

Thank you for your patience while our engineering team worked to resolve this issue. A fix for this issue is now available in:

• Android Studio Iguana | 2023.2.1 Canary 7
• Android Gradle Plugin 8.3.0-alpha07

We encourage you to try the latest update.

If you notice further issues or have questions, please file a new bug report.

Thank you for taking the time to submit feedback — we really appreciate it!

Hi - thanks for following up.

Can you provide a thread dump so we can see if this is the same issue?

Actually I have one here:

Hmm, could still be useful to have yours. I created mine by artificially inflating the time it takes to do the rendering of the drawable, but it still shouldn't have deadlocked as the autocomplete is no longer waiting on the rendering of the drawable.

If you have a consistent repro or a thread dump, I'd much appreciate it.

I've been seeing something like this in the last few major versions of AS (including 2022.3.1 Patch 2) (and last few of macos - now 14.1). After Force Quit, all Local History for all files is gone.

I haven't experienced this issue since updating to Hedgehog.
