cryoSPARC 3.2 cannot start -- command_rtp: ERROR (spawn error)

I have been using cryoSPARC 2 for a while and just did a fresh install of cryoSPARC 3.2, and it stopped working. I installed cryosparc master using the standalone method which went well but does not start. I tried a few times, including rebooting my workstation but ended up with the same problem. I’d appreciate very much any ideas to solve this!
>cryosparcm start
Starting cryoSPARC System master process…
CryoSPARC is not already running.
database: started
command_core: started
command_core connection succeeded
command_core startup successful
command_vis: started
command_rtp: ERROR (spawn error)

OK I got it to work. I needed to bypass proxy settings for the hostname.
