I removed all extensions, an this seems to solve the problem. I then reinstalled my extensions one by one. The extension causing the problem seems to be: NordVPN Connect by poilrouge. When running "NordVPN Connect", error only occurs after screen lock and wake up. When error occurs, there are no error messages, and no high CPU load.
