VS 2022 errors ENC0020, ENC0021 even though code changes were made prior to starting debug session

Does anyone know how to solve this problem?

I have a solution with multiple projects, including: 2 Class Libraries, 1 REST API server, 1 Web server, 2 REST API clients. I made a change in the code underneath REST API server - I changed a function to async, and added await to the calls to it.

I made the code changes while NOT debugging - it was not in run mode. I then cleaned the entire solution and did a rebuild all. However, when I press Run to debug, I get the following errors.

HOWEVER - the code runs. I can set breakpoints and step through the new code I added, it executes. No idea why it is showing the errors.

It's look like a bug introduced in VS 2022 17.1.3 and 17.1.4, nothing to do except restart VS.
