Black icons with Nextcloud Hub 9 (30.0.4)

[AmbreM71]

All the icons that should be altered with this app are displayed in black, see screenshot below.

I encountered this issue in Nextcloud Hub 9 (v30.0.4)
Behavior is the same using bright or dark theme.

Same issue with v29 for me but I managed to disable it for all other users. Would be nice to figure out why this happens though.
