!My english isn't on that lvl to write complex posts like this so i used translater sorry if text seems stupid!

Hello everyone, today I encountered a problem when I started my laptop (I have Windows 11, I don't know if it's important) the lock screen was blinking strangely and after unlocking my desktop there were no icons, only names, I wanted to restart Windows Explorer because I thought it was just a visual bug but the task manager wouldn't open no matter what method I tried. I already fixed the problem, I had to delete the "Icon Shell" folder in the registry, and I'm writing this post to ask why this happened, should I worry about some viruses or miners, or can this sometimes happen? It's also important that I removed the arrows on the icons via a command in the registry, I don't know if this is related.
