Ipykernel disconnected

[Dolarn]

Hello, im all new to this , i installed anaconda and run Jupiter Lab for 3 days (all was good ), after i delete some files unconnected to anaconda, now when i run Jupiter lab i see ipykernel connecting than ipykernel disconnected. I reinstalled like 5 times in different folders, but it doesnt help.

Can anyone help ?

any kernel errors i encountered so far had some helpful error messages on the console/log.
if that does not help, you could post your log messages here and maybe then one might be able help.
