Rasa X OS Error handle is closed

Good evening everyone, rasa x no longer works on my windows 10 computer. I tried various ways and searched the internet without finding a solution. The problem happens with all my projects both in the PC command prompt and in the virtual environment. Also in pycharm. Someone kind to help me? Here is the problem.

C:\Users\Mario\CHATBOT\1_BASE>rasa x

Sorry, something went wrong (see error above). Make sure to start Rasa X with valid data and valid domain and config files. Please, also check any warnings that popped up.

It looks like there’s a problem starting the event service.

Could you try the Quick Install setup which uses Multipass?

Hello Stephens, Thanks for the reply. I tried reinstalling rasa and everything else without being able to fix the problem. Then I tried on another pc like mine with the same operating system and I saw that rasa worked correctly. So I reset my operating system. Now it’s ok. I think my antivirus probably deleted some executable files. Thank you very much. Bye
