@jstagno What version of CryoSPARC do you use? If you use v4.5.3, you may want to apply patch 240807. If your CryoSPARC version is below 4.5.3, you may want to upgrade CryoSPARC to the latest version. If you experience this issue on either v4.5.3 (with patch 240807 applied) or v4.6.0, you may try restarting the command_vis server:
cryosparcm restart command_vis
