Resolution Note:
Mesh optimization works by reading usage data from materials & shaders, so if those two pieces of data are in different bundles, it won't work.
There are some options to fix this issue:
-Not put the material in a bundle leave it as none. When building the bundle, it will put the material in the correct bundle.
-Disable mesh optimization.
-Switch to Scriptable Build Pipeline, it handles dependency better than the current build system.
