Crash on boot of 1.20.2 regardless of installed shaders or resource packs, which instantly gets solved by uninstalling ETF & EMF

But I don't get a separate crash log.

are you using ETF's 1.20.2 specific build? or its 1.20 build?

this is a crash the 1.20 build would give

future uploads of the 1.20 builds will prevent loading in 1.20.2, they still allow loading attempts in future version as the last update was before 1.20.2 released
