When running nomad sculpt on Monterey 12.7.2 (on iMac) and using its GPU named AMD Radeon Pro 580 Compute Engine it runs well, but on Monterey 12.7.4 in the Powerbook 2015 with GPU Radeon R9 M370X it only tries to start, but then stops

THE PLATFORM: MacOS 12.7.2 vs 12.7.4
NOMAD APP VERSION: 2.8.2, 2.9.5, 2.9.8

It even does not work when granted full hard disk access with approx. 400GB free space

Could you try 2.3.25 or 2.4? To see if it launches.
