I’ve had this happen as well! Had you just opened Blender? Asking because I have also had an issue with items in the Asset Browser not loading but if I restart Blender everything loads fine. I think the two issues are probably related. Unfortunately, I can’t recreate the issue, aside from that it’s more likely to happen when opening Blender for the first time after my computer has been off, and thus don’t feel comfortable posting it as a bug on the dev site.
