Editor crashes with no crash log

after I updated to version 4.22 and convert my project strange crashes appeared. The editor crashes randomly with no crash log. I need to open task manager and shut down the process whic is not responding but still use big procentage of my processor. I have notices that crashes appears most often when i press f11 to exit full screen mode and sometimes when i duplicate or add object in the scene. When i launch the project again there is a chance to stop crashes for the next session.
