Screen lock up and Anti Tracking fail

My windows 11 lock up randemly without warning, almost always while mouse movement. The Windows Realibility check points to Avast Anti Tracking stop working…. Can I turn off the Anti Tracking function? but it would defeat the purpose of using Avast? Or it is actually saying some other problem? I have tried Avast repair but no help, also updated windows, driver.. etc… Anyone has the same experience?
