Muse Style Trainer Unusable

Hi all. Whenever I try to use Muse style trainer and add images, everything seems to crap out. Whether I add one, several, from project, from my HDD, sometimes even just opening the style trainer - I get a stream of errors and nothing happens. Sometimes things freeze.

Unity 2023.2.3f1
Muse 1.0.0-pre.2 (common library/texture)
macOS Sonoma 14.1.2 on M2 Pro

Any ideas? It’s totally unusable, there’s no point subscribing for me at the moment.
