Welcome to the forum @lix .
What version of the CUDA toolkit is configured on your cryoSPARC worker(s)?
To find out, execute these commands in a shell on the worker:
Is the installed version supported by cryoSPARC?
If not, you need to locate or install a supported version of the toolkit, and then run (under the same Linux account as the cryoSPARC instance)
/path/to/cryosparc_worker/bin/cryosparcw newcuda /path/to/cuda
(see guide).
