We appreciate the information that you've provided, Seppe. We suggest to proceed with performing a clean boot first. This will only isolate any software conflicts and will not remove any files. When you start Windows by using a normal startup operation, several applications and services start automatically as well and then run in the background. Programs such as basic system processes, antivirus software and system utility applications running together at the same time in the background can trigger software conflicts.
Let us know how it goes after performing the suggested steps.
