the game instantly saves and crashes when trying to render slimes (?)
I was excited to play tinkers construct after so long but about 5 minutes in, the game closed by itself (1st crash report)
I tried updating to the latest forge install and generated a new world which instantly closed (2nd crash report)

included : 2 crash reports
https://pastebin.com/tyxLYczw using forge 36.1.10
https://pastebin.com/0E2Pmg2V using forge 36.1.18

Versions:

• Minecraft: 1.16.5
• Forge: 36.1.10 & 36.1.18
• Mantle: 1.6.97
• Tinkers Construct: 3.0.3.152

Confirm below that this issue is not covered on the roadmap or "Whats New?"
I couldn't find any similar issue and it's kind of a game breaker

Can it be reproduced with just Tinkers Construct? If not, list the other mods required to reproduce the issue.
no other mods were used : only tconstruct, mantle, forge and minecraft appears as mod loaded in game
