I know Ive seen other reports of 1041 issues. I would suggest uninstalling and reinstalling the 1041 module.

Close ProSeries 2019.   Use Windows Add/Remove Programs, find ProSeries 2019 and click Uninstall.  It will act like its going to uninstall the whole program, dont panic, it doesn't.  A new window will open with a list of different modules to chose from, find the 1041 and uninstall it.   You wont lose your client files.

Restart the computer and then open/log back into Proseries 2019.  Go to Update > Select and Download New Products and be sure 1041 is checked, hit Next and download and install the 1041...see if you have better luck.
