I have the same issue. I got the following message: [MTLDebugTexture removeUsedRenderTarget:slices:]: message sent to deallocated instance 0x13179f4c0. Metal API validation was enabled. I disabled it and did some testing and was not able to reproduce the bug. After turning on Metal API validation again, the bug was there again after a couple of tests.
Edit: It started when I starting using NavigationView in my app (I was managing navigation without it before). I am wondering if it has to do with that.

I cannot offer any help, but I have the same issue. I noticed that it appears when I switch the view while the cursor is still in the text field. I tried adding resignFirstResponder in different ways, it did not help.
It seems to disappear if I set:
textField.autocorrectionType = UITextAutocorrectionType.no
I tried that because of the UIKBautofillController pointing to the field in the memory debugger.
