Can this still be reproduced using the latest master version? I am unable to reproduce it.

Not able to catch it again on latest master (ILSpy version 9.0.0.7810-preview2+280d17332f81916e9f18a363fc3264df32e59b98)

thanks! closing

well, having some time and desire and ... was able to reproduce it... steps: just walking on assemblies references deep diving into lower levels,etc:

Maybe stack tracke will help to understand how it happens?
