"Could not retrieve md5"; brushes not loading on 6.0.1

Not sure if I’m blind or not, but some brushes (seems random which ones,) will simply refuse to load into v6. I know it’s a nightly build so I’m not really bothered by it, but wanted to post the issue in case it can be reproduced/something else is going on internally.

All that the logs show is “Could not retrieve md5 for resource (…)”. The particular culprits in my case are Memileo’s full impasto release and the WIP 360 light bundles, and a part of JP’s bundle.

Running on CachyOS, KDE, if that helps!
