Database error after v4.1.0 update

[wtempel]

It is possible that the coordination between some CryoSPARC-related service processes has failed.
Under the Linux account that usually runs CryoSPARC (victor?), please can you run

@wtempel

1. cryosparcm stop
2. Identify CryoSPARC processes that were not terminated as expected:
   ps -u $USER -opid,ppid,cmd | grep -e cryosparc -e mongo
3. Determine the process IDs of potentially remaining supervisord and mongod processes and, if such processes exist, terminate them
   kill -TERM <process id>
   (but not kill -KILL or kill -9), wait 10 seconds and confirm that no CryoSPARC related processes, such as supervisord or mongod remain:
   ps -u $USER -opid,ppid,cmd | grep -e cryosparc -e mongo (again)

If that second ps command doesn’t show any more CryoSPARC-related processes, please try
cryosparcm start
Can you now connect to the CryoSPARC web interface?
