Issue: Fatal Exception: NSInvalidArgumentException -[NSNull encodeSuccessEnvelope:]: unrecognized selector sent to instance
Labels: c: crash,platform-ios,engine,a: production,P2,team-ios,triaged-ios

## Steps to Reproduce

Unfortunately this is not reproductible directly as it happened only in `release` mode so far, but i have got a crash similar to #95565.   
I have fixed the problem in #95565 by releasing a too high memory thread.  

I am not doing anything "unusual" anymore in my app that would lead to this crash so i have no much lead...
