The culprit ended up being a faulty Wacom driver service called: Wacom Tablet Service for ISD

Disabling that solved the issue. The fun part is that I don’t use touch-screen features, nor have a Wacom tablet. Nonetheless, this solved the issue.

Sorry for bothering you for this issue. The first thing I obviously thought of was a problem with spyder, but this ended up being completely innocent.

Thank you for the support Luca

Glad you found the culprit and thanks for letting us know about it.

I guess you fought a lot to finally uncover the real cause.
