Studio 22 wont start "A entrada não é uma cadeia de Base-64 válida..."

I know this question has been posed before, but I have tried the suggested fixes and they do not work.

Furthermore the description of the localization files doesn't match mine.

They seem to have been sent to a diferent location by windows most recente update.

Is there any other way to fix this? I have restarted the computer, unistaled and reinstaled Studio and nothing seems to work.

I have a deadline for today at noon and I'm running out of time!

Could you please help.

Thank you

Rita
