Hi everyone, I was using VS2022 version 17.14.2.
However yesterday I was able to upgrade my VS2022 to version 17.14.3 and
after rebuilding everything the issue has gone.
I repeated the VS 2022 update and rebuild steps also on the other computers
I was using in order to make sure the issue was not related to a single
machine and I can confirm the issue is gone. Also the original application
is now building with VS2022 version 17.14.3.
Kind regards,
Guglielmo
