Adobe Reader does not verify electronic signature

Adobe Reader installed on one of the computers does not verify electronic signatures. On another computer, the same program verifies the signature and confirms its correctness. I did an update of the program, certificates and it still does not work. What else can I do?

What exactly is the message with which that Adobe Reader instance rejects the signatures in question? Can you share an example PDF?

Attached is a document signed with a qualified signature. On all other computers it displays "Signed. All signatures are correct." Unfortunately, on this one computer there is the same file and it displays "Al least one signature has problems".
I also noticed that on the other computers among the certificates there is a certificate starting with a string of digits and ending with the email address of the person to whom the computer is assigned (screen attached). And on the computer where Adobe cannot verify these signatures there is nothing similar.

What does the problem computer show there? (Please make sure to set the Adobe Reader language to English for the screen shot.)
