Power BI won't launch

[Anonymous]

Hi

I was working normally with power bi desktop (server version) (May 2020) and applying some modifications to my dataset after I clicked the "Apply and close" button, power bi gave an error and closed, after trying to open it again keeps loading and after 5 minutes gives the attached error (even opening a new report or data model):

Feedback Type:
Frown (Error)

 have tried the following to solve the problem:

• reboot my machine
• uninstall power bi desktop and reinstall it again
• download latest version available (October 2020) -> same problem with same error
• uninstalled (October 2020) version and reinstalled the May 2020 version with the same error.

so anyone has any idea what the cause is, and how to fix it.

Thanks in advance
