Windows print queue not properly created

I am trying to create a printer/print queue in Windows, for a printer connected to a RaspberryPi running Cups. I have followed this procedure for setting it up:https://techblog.paalijarvi.fi/2020/05/25/making-windows-10-to-print-to-a-cups-printer-over-the-network

However, it does not work. The printer is somehow defined in Windows (it appears on the "Printers and Scanners" page), but when I try to open the print queue, it fails. I have dived into the EventLog, and found several error messages, whereof I think the key ones are...

From Applications and Services Logs/Microsoft/Windows/PrintService/Admin - this is logged when I created the printer/queue:

Log Name:      Microsoft-Windows-PrintService/AdminSource:        Microsoft-Windows-PrintServiceDate:          28/03/2024 02:21:51Event ID:      808Task Category: InitialisingLevel:         ErrorKeywords:      Print SpoolerUser:          DESKTOP-8V33TTS\knutComputer:      DESKTOP-8V33TTSDescription:The print spooler failed to load a plug-in module C:\WINDOWS\system32\spool\DRIVERS\x64\3\E1YUICBCE.DLL, error code 0x5AF. See the event user data for context information.

The other one is logged when I try to open the print queue window.From Windows Logs/Application:

Any ideas what is wrong (and perhaps even better, how to fix it)?
