Creating signed PDF Documents Error

For several days I am suddenly not able to create signed pdf documents. It always generates error while signing. I tried even older versions (4.3.0) on three computers with different OS, on different networks, with the same error. Nothing changed in my environment, maybe only some windows updates.

Has anybody experienced the same issue, or resolved it?

Thank you.

Bellow is log:
