I have downloaded symbolicated crash report using Xcode but unable to understand it as in backtrace it shows below method where it crashed:
-[UIView(Internal) _addSubview:positioned:relativeTo:] + 132 (UIView.m:16297). However, I can't find that specific method in my code where exception occurred. Below is the crash report:

Its because this crash is possibly a side effect of your view configuration and happens in an Apple framework, noticed you are also using a beta version, try running the same code in ios 14.6, if you can reproduce the crash with the device connected you can enable the Exception breakpoint in Xcode to isolate the line that triggered the chain of events.
