G-Raid with Thunderbolt Configurator crashes under Catalina

Pretty much the title.

The drive is connected to a MacMini 2018 using the Apple Thunderbolt 2 to Thunderbolt 3 adaptor.

The drive mounts and works properly otherwise.

It asks for the password, then displays the app window, takes 5-10 seconds to recognise the drive - 16TB Thunderbolt 2 G-RAID, and then crashes. It crashes in about 10 seconds no matter what - if I do nothing or press the Configure button. There is a time window that might enable me to change the RAID config (currently RAID 1, want to change to RAID 0) but I am afraid it’ll crash midway and brick the drive.

Restarting the Mac Mini does not help.

EDIT1: Disconnecting Thunderbolt and connecting via USB - same result.

That’s the only error code/message that appears for you ?
