What happened to Windws 11 update last September?

Update done as posted then Problem.
My HP printers were deleted. I've been able to find the apps for them for Windows 11, I was able to install them, last week. then print. I restarted Dell machine and the printers were deeted. IS there a problem with Windows 11 update?
HP Color 400 and MFP M277.
Printers work with a Dell laptop Windows10 on same network.
Can that be fixed?

The driver I use is the HP universal printer driver, downloaded at HP-site.
The newest driver is this one:

I just installed that on a testsystem with Build 23H2 22631.3085 and have no problems at all to print to my Color Laserjet CP1515N.
On my normal system I use an older version of the driver, because that version still has reports about paper tray empty/toner empty in the notifications area.

I found this about a recent problem in the HP app on the HP site:

PS. I don't use any app to print to my HP printer, just a universal driver.
That's because I don't want HP to interfere with my printer settings, drivers or even firmware of the printer. I have that printer since 2008 and would like to keep it as long as it is functioning, without HP forbidding/disabling the use of alternative toners!

That update did have problems with deletion of HP printers.
Some suggestions:
