Any solutions for this problem, please ?

Thank you very much in advance for any help.

Any news about this issue ?

leads to my opinion, that the CA- and SSL-certificates are not properly installed or do you have file-encryption installed and activated?

Maybe this issue is related to your problem:
https://github.com/nextcloud/server/issues/57362
(read it to the end)

I tried to decrypt my file with the encryption recovery tools and I still have the same problem.

ERROR: AN ERROR OCCURED DURING THE DECRYPTION

So the title of this thread ist wrong - should be “Error decypting files”.

Did you try to follow the workaround in the linked above Github-Thread?
Your posted above error message seems to be certificate-related. - But I can’t help you anymore, because I never did work with Nextcloud file encryption-seems not to be safe enough to handle with.
