Spinnery (which is discontinued but embedded in Identity) crashes when clicking on it in the mod list (with mod menu) and when opening the player inventory.

Also, you haven't listed spinnery as a dependency on curseforge, and Fabric doesn't report what jar file it's in, which makes this sort of thing harder to track down than it should be.
I tracked it down with grep -r spinnery *. Removing your mod removes Spinnery.

see Mixinors/Astromine#311 for logs and crash reports.

Having the same problem when tring to make identity to work in 1.16.3. Don't know why spinnery is discontinued.

Mixinors/Astromine has switched to vini2003/Blade, but Blade seems not support TextField...

(Or how about switching to CottonMC/LibGui ?)

Fixed in 1.9.1~
