Seemingly infinite (or just really, really long) hang on first launch

After finally figuring out how to get this working with my AMD RX 5700XT on Ubuntu 22.04.4, I was able to get the web interface running.
Queuing my first prompt resulted in this:

`$ HSA_OVERRIDE_GFX_VERSION=10.3.0 python3 main.py >
... got prompt
model_type EPS
adm 2816
Using split attention in VAE
Working with z of shape (1, 4, 32, 32) = 4096 dimensions.
Using split attention in VAE
clip missing: ['clip_l.text_projection', 'clip_l.logit_scale', 'clip_g.logit_scale']
Requested to load SDXLClipModel
Loading 1 new model`

And it just hangs here, for quite a while! Do I wait it out? Or is something stuck? It's super late enough in the day I'm much too tired to keep troubleshooting, so I'm making a GitHub issue and seeing what this thread looks like tomorrow. It's probably some no-brainer problem that I'm too tired to notice right now. :(

Here's any relevant info that may help.
