Of course, here you have.
It’s on Windows 10 Pro, both updated frequently.
One of those not working has a reference to the folder where .NET Core SDK 3.1.411 lives.
The working one has no reference in .NETCore CLI, as hasn’t other of those not working.
About the logs, they are so so different.
The working one throws a long log, full of Omnisharp debugs.
Any not working PC shows a scarce log, wherein the only OmniSharp reference says “‘OmniSharp’ skipped because there is no related file in current project”.
PS Maybe the main log line which makes the difference is “0 files indexed” in those not working, just before the OmniSharp missing warning, whereas the working one says “1 file indexed” before “Execute Sensor: OmniSharp” and then the whole analysis starts by Omnisharp.
I can send you both of them as well as plenty more info if you need it.
