this is a dupe of #3274 please see https://github.com/OmniSharp/omnisharp-vscode/issues/3274#issuecomment-530520009 or try installing the latest beta from https://github.com/OmniSharp/omnisharp-vscode/releases/tag/v1.21.3-beta1

Thank you. I solved it by adding "latest" to "omnisharp.path".

I had a specific beta version I added sometime ago because of an existing bug.
