Can't import photos into Lightroom Classic

[Kateli]

Hi, 

I can't import my raw photos shot with my Canon R into LC. 
I could this morning and now it simply won't work.
I get error messages...
Can anybody help me please ??

Is the camera card still working properly? Is the card reader (if you are using one) working properly?

Also, please provide the following information

Can your operating system view these files and move them to a your computer?
