Crashing Signs

[Zartrix]

When placing either Ancient or Gloom Signs/Hanging Signs, the game crashes.
The log is also spamming a lot about missing models for a blockstate (using Enhanced Block Entities? I don't have that installed.)
Log output
Crash-Report
Using latest Fabric and Excessive Building version on 1.21.1
