MS Camera Cannot Be Found

I will skip the lengthy reasons why I tried to install the MS Camera app on my wife's Dell XPS8950, which only somewhat worked. I downloaded the file from the store and ran it, bu then when I tired to open it I was informed that it could not be found. A quick search for that malady said that antivirus programs could cause this. As my Windows11 25H2 shows that it is System Mechanic which handles this. Having not tried for sometime to disable System Mechanic, I found the instructions on-line from IOLO, which are apparently out of date, as none of the steps could be found. Giving up, I turned the program off and tried again to find the camera.

That search did not locate the camera, which other source(s) showed that it was installed, I restarted the computer and as it was time to log on here, you may notice that that was accomplished, so I am now seeking guidance on now to remove the lens cap, as it were, for the MS Camera.

As is my wont, I am stating my appreciation in advance, lest I forget to so do once the malady has been overcome.
