I now seem to be having this same problem. It prints to a printer, but when a PDF driver is selected, after it completes the output, it waits a few moments and then crashes with the following message:

I'm not sure why it reports this as 1st January 1970.
The FTN95 version is:
Silverfrost FTN95/x64 Ver 9.10.4.0
I'm running Windows 11 Pro, Version 24H2
It happens whether I compile with Release, Debug or Checkmate.
