this keeps popping up when i open my PC, i've already uninstalled everything and it still pops up

this pops up. when i put in my code, it says this error. if i press the X to close the pop up that should close it, it still brings me back to this.
i can currently only close it in task manager.

i have checked my PC and everything should’ve been deleted, even from the trashcan.

What code are you putting in? Do you mean this is happening only after logging in or…?

I’d start with a full power cycle and if the issue persists, try installing the latest version found on the website.
