Basically the game freezes using an inscribed key on portal keyhole and crashes.

Forgot to add it's on forge 1.19.2 and the mod version is 179

The call stack gives me the following information:

• My mod was trying to build a dungeon.
• ... trying to build a room
• ... trying to spawn a mob in that room
• ... then a mixin is trying to play a sound effect (even though no one is around)
• ... the sound effect is picked via the spawn egg, which is null, and crashes

The mixin that is crashing is called "SpawnEggUseSoundMixin". Does that help? I would ask that mixin's author to check for null to avoid the crash. Give them the same crash log.

Another possibility is that the mixin is also innocent, and that you are using a mod such as "Bad Mobs" to unregister certain vanilla mobs. Lots of mods are not coded to expect minexraft:zombie to be null, for example.
