Errors while reading the F# metadata using compiler from SDK 6.0.100-rc.1

[gsomix]

Mysterious warnings occur while compiling pulsar-client-dotnet. Please take a look at build log from #12189:

warning FS3186: An error occurred while reading the F# metadata node at position 4 in table 'itycons' of assembly...

I reproduced it at local machine. Steps:

git clone git@github.com:fsharplang-ru/pulsar-client-dotnet.git3
git checkout 4e353ea
dotnet tool restore
dotnet restore
dotnet build -c Release

Expected behavior

Compilation completes without warnings and errors.

Actual behavior

There are warnings in build log:

I do repro this. The warning can be safely ignored though I'd like to get to the bottom of it for sure.

#12195 suppresses this warning by default, as it has long proved harmless. If we get a repro where it causes a problem we will fix it
