[macOS] Inconsistent crash in objc_msgSend/objc_retain when previewing Animations with Animator window open

Animation

Apr 27, 2020

How to reproduce:
1. Open tester-attached project(AnimatorCrash.zip)
2. Enter Play Mode
3. In the Animator window, switch to the 'Parameters' tab
4. Toggle the only parameter off and on; wait for the animation in the Game View to finish each time
5. If the crash does not occur shortly, restart the Editor and repeat step 1-4

Expected result: the Editor does not crash
Actual result: the Editor eventually crashes

Reproducible with: 2019.3.13f1, 2020.1.0b9, 2020.2.0a11
Not reproducible with: 2017.4.40f1, 2018.4.23f1

I'm having the same issue on Unity 2019.4.7f1

when editing animations then hitting play, unity will lock up for a while then spring back into life.

Often Unity will just crash when hitting play.

at least once I got a KP and Unity crashed Catalina.

Hello! I had the same issue but it was connected with metal renderer interaction. After disabling metal in the editor crash is gone.

same issue here. Both on macbook pro and iMac.
It also request developer tools update.

Run this command to stop the popup at least:
sudo /usr/sbin/DevToolsSecurity --enable

as a workaround, dock the animator and animation editors in the the same tabbed window, so you can only see one at a time. for me this has stopped the crashes completely.
