SOLVED- Crash opening editor 4.20.2

With update to 4.20.2 I can no longer open a new project, nor open a project made with the 4.20
When I open the editor, it comes to 72% closes and does not give me the crash report, just a windows screen that says it is sending a report to microsoft!
I use a MSI GT75VR 7RE Titan PC with a GTX 1070

------- Solution ----------------------
Uninstall the engine 4.20.2
Reinstall the engine 4.20.2
With this procedure everything is back to work
Thank you

Same problem. I can’t even open new project. Epic, what are you did???
