GLSL 3.30 is not supported
I use vrtualbox windows guest OS, which doesn't support OpenGL 3.3 I encountered with issue:

Could i use application with lower version of OpenGL ?
Does an override resolve your issue:
MESA_GL_VERSION_OVERRIDE=3.3 MESA_GLSL_VERSION_OVERRIDE=330
I notice that your version of Mesa is from 2018 and Mesa has seen rapid development. Does upgrading Mesa resolve your issue?
