Hey, Hanno from Margelo here who build the library for profiling. Feel free to assign to me ✌️

[zanyrenney]

thank you @hannojg

[hannojg]

Update: I am able to reproduce and working actively on it!

[hannojg]

Under the assumption that this is a react-native/hermes problem (as the stack trace points directly to hermes, not our library) I tested the bug on the RN 0.76 PR where i am not able to reproduce the problem anymore:

• Upgrade to React Native 0.76 #51475

CleanShot.2024-11-27.at.10.37.47.mp4

(On the main branch the app usually crashes instantly for me, but in the PR it seems fixed)

I would suggest to put this on hold for the mentioned PR.

(We could also make a new adhoc build from the mentioned PR (previous ones are too outdated) and then maybe @zanyrenney / @mountiny you could test the iOS adhoc build on your physical phone to verify that the problem is fixed in the PR?)

Put it on hold, I cant test on physical device at the moment unfortunately
