Cannot open cmd prompt in admin mode

I am using win 10 pro. My initial problem is I cannot display list of wifi networks. I cannot open cmd prompt in admin mode. I've used all the trouble shooting steps on this site and nothing works. Short of throwing this PC out the window is there anything
else I can try?

 

.txt will open open in Command Prompt

I don't know why but no matter what I do .txt will only open in CMD prompt and I have right click and go to open with every time which is annoying cause I use .txts a lot for noting stuff down in.

 

Random CMD prompt opens randomly and closes.

For the past couple of months before I installed windows 11 and was on windows 10 a cmd prompt would open, interrupt Fullscreen then close a second later. The name of the cmd prompt was a file directory to something in my AppData folder but checking for the file it doesn't show up even when looking for hidden files. It has a random name which is just random characters and sometimes it stays on long enough for me to see it says something like .NET Framework. This is an annoying issue as I haven't been able to use Fullscreen for things like games because it closes it once it opens. I have ran multiple full scans with windows defender and malwarebytes to no result. I have tried to screenshot it but it closes too quick.
