It’s not related to big sur as you can try to reinstall previous OS and it still shouldn’t work. Apple is aware of this issue but they don’t seem to care sadly…
Do you have the 13 or 15 inch model?

Hey thanks for your reply. So I reinstalled Sierra and checked the system log like you asked and I only have a dfrdisplayregisternotification but no error. Should I look for something else? Thanks for your help
