Need help with PSE and Raw

I have used raw files with PSE versions for more than a decade. Suddenly, my PSE 2023 won't load raw images from a Canon that it used to load last month. It says I need to load to Camera Raw Update, but when I try to load it I get one error that it is already loaded and then a second that my administrator prohibits loading it. So I spent hours with my system administrator yesterday, who said he is doing nothing to block it, but he couldn't it to load, despite reinstallign PSE. So today I completely rebuilt my XPS laptop with Windows 11 from scratch, no institutional limits, running it as administrator, loaded PSE 2023, then the Raw Update, still no luck. Now I just get the error that I need to install the update, but when I try, I get the error that it is alreay loaded. I am totally flustered and woudl be grateful for any help.
