CIS 2025 (v.12.3.3.8140): Error when decoding a file to be sent for analysis

I took an example, I have an *.exe file, and it was not sent to COMODO’s servers.
That’s why I’m saying there is a problem.

Another example that the problem continues, they are stopping sending some.

Now I took some examples with different extensions, look at the result.

What could be the problem?
I think it’s the COMODO servers, because I didn’t have these errors before.
Did it happen after the certificate was revoked or is it the servers?
