MC 1.19.1
Fabric API 0.58.5
ETF 4.0.1
Puzzle 1.3.4

To reproduce simply have the mods installed and click on the puzzle icon in video settings. Reporting here and not to ETF because ETF alone works. ETF also doesn't crash in Mod Menu.

Hi, I have the same issue :(

ETF has had to change some file locations due to using architechtury now and puzzle needs to use the ETFApi.class (https://github.com/Traben-0/Entity_Texture_Features/blob/master/common/src/main/java/traben/entity_texture_features/ETFApi.java) to fix it, i've tried to make a PR for this but my fork of puzzle doesn't build for some reason

got it sorted there is a fix in PR #43
