You have a driver mismatch

[ 1179.761696] NVRM: API mismatch: the client has the version 510.60.02, but
NVRM: this kernel module has the version 510.47.03. Please
NVRM: make sure that this kernel module and all NVIDIA driver
NVRM: components have the same version.

Please uninstall all nvidia packages and runfile installations and cleanly reinstall the driver from repo.
