Bug iOS app built with Unity 2020.3.42 always crashes on exit

After upgrading from 2020.3.18 to 2020.3.42, my iOS app now crashes 100% when taskkilling.
I have tried it on multiple devices and all (all iOS16).
Do you have any information about this?
This thread is similar to this one, but the graphics had nothing to do with it, so I started a new thread.

I had believed this problem to be widespread, but apparently not.
It takes a long time to create a minimum reproduction project because I have no idea what triggers it.
If anyone knows anything about this, please comment.

 

having the same problem on Unity 2022.2. My app generates a crash report with SEG FAULT on calling Application.Quit().

 

From my testing, this problem does not seem to occur with 2020.3.41.

 

↑ was my mistake. in 2020.3.41, the frequency has decreased. However, it does occur.

 

Same problem. It also happens on iOS15.

Any news here? Has anyone already tried Unity 2020.3.43?

 

same issue here. happens in most iOS devices after minimizing and closing the app from the tray. upgrading from unity 2019.4.31 to unity 2020.3.42

update:
problem seems to go away after downgrading to 2020.3.41

 

2020.3.43 also has the issue.
(Upgrading 2020.3.25 to 2020.3.43)

 

I do not think this problem is recognized by Unity.
I sent them a bug report, but I was a bit too busy to make a minimal reproduction project and closed it by them.
If anyone has a minimum reproduction project, I would appreciate it if you could send a bug report to Unity.

 

same issue . (Upgrading from 2020.3.3 to 2020.3.42)

 

When I call Application.Quit() on iOS, I always get a fatal error exception in 2020.3.43

So I downgraded to 2020.3.41

 

Can it only be solved by downgrading?

 

I have the same crash with 2020.3.43f1 on the app quit with Windows Standalone. Unity 2020.3.38 didn't have this issue.

 

Update.
Maybe, but I think it's the same issue as this thread.
