Please can you describe when you observed this error. I would expect this error to make the GUI inaccessible, and may be a separate issue from
Undefined symbol: cuIpcOpenMemHandle_v2
Please post the outputs of these commands (run under the Linux account that runs the CryoSPARC instance):
cryosparcm status | grep -v LICENSE
ps xww | grep -e cryosparc -e mongo
