Game crashing when trying to enable shaders : "Couldn't load vanilla shader from effective:shaders/core/soft_particle.fsh"

[ErranticSam]

My game crashes when I try to enable the shaders and Effective is enabled too, and this error is showing :

foundry.veil.api.glsl.GlslSyntaxException: Invalid Version: #version 150. For input string: "150" at position 22: #version 150#line 0 1<--[HERE]

I can safely enable shaders without Effective enabled.

EDIT : seems to be the same error code than #298

EDIT 2 : forgot to link the error log
