Nvidia RTX 3080 TI
Have 3 monitors (2 monitors + 1 TV)
Under System > Display > Color Management you can see the color profile is selected properly.

You can see its visible here, no problem

However it is invisible in Displaycal

For some reason all profiles that originated for Pixio monitor were under the Beyond TV… so I had to manually delete them. Also all other monitors show their own listing properly.

I manually selected the profile using windows, and its still not showing inside displaycal
I’m seeing a red C and line in the loader in the taskbar

DDU did not fix
Is this program out of date?

That may happen when output is switched between clone/extend, either by user or by OS mistake when pluging display.

That means displaycal has no access to VCGT in GPU to load grey calibration. Testing Argyllcms commandline should show similar symptoms (hence this issue has nothing to do with DisplayCAL on a first diagnosis).
There is Argyll 3.5.0 and dispwin commandlike executabe may be blocked by some AV/security tool.
To to classic windows control panel, color management, advanced an make sure that you DO NOT have enabled use windows calibration checkbox on the bottom. That option if enabled gives VCGT control to the innacurate VCGT loader on Windows OS, blocking the use of DisplayCAL loader.
