Have you tried Rollback the Windows upgrade ? When you upgrade from Win10 to Win11, Windows will usually saved the Win10 in [C:] drive...
If you happens to have an old copy of the drivers, you can just used that drivers. Win11 will just allow the installation, some compatibility may occurs.
Another methods, try -->

Hope this helps...

Try this method, also another trial & error process :-
1. Goto --> Computer Management --> Device Manager
2. Look for the missing driver with "?" mark, Right-Click --> Properties --> Details
3. Under "Property" drop-down box, Select --> Hardware Ids
4. Copy the first line of the listed value.
5. Open browser & Google the copied value.
6. Try look for compatible drivers or best if have direct Manufacturer website to download the drivers.
Some downloaded drivers doesn't have the exe/msi installer, usually zip files. You need to extract the zip file & then manually install drivers :-
1. Goto --> Computer Management --> Device Manager
2. Look for the missing driver with "?" mark, Right-Click --> Properties --> Drivers
3. Click --> Update Driver
4. Select --> Browse my computer for drivers
5. Search for the downloaded & extracted drivers, if a compatible drivers is found by Windows, then you can select it to install.
Also, you may need to restart the computer after each installation to confirm its working/installed correctly. If you some how installed a drivers that are not compatible with your hardware that maybe... maybe... caused a BSOD, then you need to restart the computer into "Safe Mode" and uninstall that drivers & after that restart normally.
Hope this helps...
