Why has my BU40N external Libredrive drivers stopped working (Code 39)?

It's been working years on this machine without problem... now Windows is saying some driver is missing?
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
Object Name not found.
In events log for driver it says:
Device USBSTOR\CDROM&VEN_HL-DT-ST&PROD_BD-RE_BU40N&REV_1.04\4D4F344B435449313631342020202020&0 was deleted.
Is it anything to do with this WinRing 0 Driver problem (https://gamersnexus.net/features/insecu ... vel1-techs) Windows removed? I see FanControl software has now moved to some new method of hardware sensors WinRing 0 Driver removed.

EDIT: Well this seems to be some problem on my main Windows 11 24H2 based machine... I just plugged the drive into my Windows 10 based PLEX movie server and it is working as normal. I wonder did some new Windows 11 update break the driver somehow. Or maybe some low level anti-cheat kernel driver from EA?
