Image Mode changed from RGB to CMYK after update and error does not let save.

[defaultctttva9a52gk]

I have a PSD file I always open, make changes to the text and save as PNG. After the last update I am able to open it, but the Image mode was changed. If I try to save it without making any changes I get the message that Photoshop could not save the file because a program error. I thought that maybe because it was changed from RGB to CMYK mode I was getting the error and tried to change the mode after flattening some layers. Nothing. The same error.

Has anybody had the same issue? Is there anything I can do to be able to work with the same file I used to do?

Thank you in advance.

I downgraded to version 21.2.4, the oldes version available and it works like a charm! What's going on?!
