I have already tried the typical "sfc /scannow" and "dism" commands to attempted a repair but no issues are detected.
Also have tried an in place upgrade to update/repair the OS that way however these errors persist.
The issue with the following DLL seems to be negatively impacting other authentication mechanisms.
credprovhost.dll
Anyone seeing something similar to this?

Hello,
If sfc /scannow and DISM didn't resolve the issue, and that an in-place upgrade also didn't fix the problem. It may indicate a more complex issue with your system.
You could consider replacing credprovhost.dll with a known good version from a similar, fully updated and compatible system. However, this is a risky step and should only be taken with great caution.
Regards,
Karlie
