Library error after installation of backup

Using Arduino IDE 1.x
1

I made an error on my disk and I accidentally deleted all my arduino files, 10min after I made a backup. I found out when I started my IDE (1.8.11) which gave errors so I copied the backup back to the original place.

But now it keeps giving me errors
The Library "CDM v2.12.12 WHQL cerfified can not be used. Library name must starte with aletter or number, followed by....

And the same for the library home automation
Then it stops. When I start the IDE again I get the same errors but then the IDE comes available

But I get a lot of errors like:
Invalid library found in C:\Users\Reinier\Documents\Arduino\libraries\Adafruit_Arduino_Boards-master: no headers files (.h) found in C:\Users\Reinier\Documents\Arduino\libraries\Adafruit_Arduino_Boards-master
Invalid library found in C:\Users\Reinier\Documents\Arduino\libraries\Adafruit_Windows_Drivers-master: no headers files (.h) found in C:\Users\Reinier\Documents\Arduino\libraries\Adafruit_Windows_Drivers-master
Invalid library found in C:\Users\Reinier\Documents\Arduino\libraries\attiny: no headers files (.h) found in C:\Users\Reinier\Documents\Arduino\libraries\attiny
Invalid library found in C:\Users\Reinier\Documents\Arduino\libraries\boeken: no headers files (.h) found in C:\Users\Reinier\Documents\Arduino\libraries\boeken
Invalid library found in C:\Users\Reinier\Documents\Arduino\libraries\Huzzah: no headers files (.h) found in C:\Users\Reinier\Documents\Arduino\libraries\Huzzah
Invalid library found in C:\Users\Reinier\Documents\Arduino\libraries\knipperstrip: no headers files (.h) found in C:\Users\Reinier\Documents\Arduino\libraries\knipperstrip

I do see the directory of the CDM and home automation library, but can't understand what is wrong, the names seem ok to me. I also do not see the libraries in my library manager to re-install them

The library name sounds more like a windows certified driver and would normally be useless to the IDE.
Could you provide a direct link to the source of that library ?

As for your other errors I would suggest to delete the offending libs and re-download them.
It sounds like your deletion may have caused other issues and that the restore may not have been from a proper backup.
