Thank you very much for your response!
Adding startup files to Windows protection exceptions and disabling protection completely did not bring success. But I found a way to isolate the editor crash error, but only for partial work.
I disabled revision version control when creating new projects, before creating a new project. Thus, we can now create a project that does not cause an error and can work in the editor without crashing.
This is a big plus, we can create a new project and continue working. The downside is that if your old projects, like mine, used revision version control, then these projects cannot be opened, loaded, or synchronized.
I really hope that this problem will be solved and we will gain access to our projects.
