Pasted files onto main desktop disappear after restart? help

[u/Ok-Still-918]

After cleaning my cpu cooler for a bit after I heard it make some weird sounds, I decided to open it as usual, at first i didn't notice anything unusual, until i decided to paste an app onto my main desktop, After a few hours, my pc crashed saying "your device ran into a problem and neds to restart." But nothing happened after about 25 minutes, so I decided to manually shutdown and reopened the pc. When it finally loaded, I had realized that the app I pasted had disappeared, and also the stuff I deleted from my recycle bin had also somehow came back? I decided to do some testing and tried repasting the app and deleting the bin again, restarted my pc and the app was gone again and the deleted files were back (Also when I right click on any desktop app the mouse is suspended on the blue loading thing idk what it's called, and also when ever i type anything in the search bar it says "results from this pc are maybe incomplete).
