PS2Keyboard Library Error, Arduino IDE

[Kilo K7ILO]

All

I am receiving the following error in Arduino IDE.
Invalid version '2021.12.16.01' for library in: (folder path of my libraries)

I am not using a keyboard at this time so i am not sure if things are operational but its kinda
annoying when compiling, even if its not related to the keyer.

And yes, I know I can just remove the library. I just dont if this is an issue or not for when I do decide to
connect a keyboard.

Thanks
