ValueError: bpy.app.translations.register: translations message cache already contains some data for addon 'mmd_tools'

Trying to install mmd tools from branch blender-v4, it returns this

Personally I would not be using MMD tools on Blender 4.0, as the developer as stated in other issues, there don't plan on releasing it unto the LTS for 4.2 comes out.

see this for more info, key word is it's under development.

There for this means the blender-v4 branch is not stable and may not be unto later this year.

Please try MMD Tools v4.x and give us feedback.

I got a similar error message while trying to update MMD Tools to 2.10.3 in Blender 3.6.11 and I'd like to know how to fix this. It happened after I removed the old version of MMD Tools, installed the new version, and tried to activate the plugin. Here's the error message I got:

Traceback (most recent call last): File "C:\Program Files\Blender Foundation\Blender 3.6\3.6\scripts\modules\addon_utils.py", line 369, in enable mod.register() File "C:\Users[user]\AppData\Roaming\Blender Foundation\Blender\3.6\scripts\addons\mmd_tools__init__.py", line 104, in register bpy.app.translations.register(bl_info['name'], translation_dict) ValueError: bpy.app.translations.register: translations message cache already contains some data for addon 'mmd_tools'

Nevermind, disabling the CATS plugin before enabling MMD Tools seems to have fixed my problem

I'm sticking to the stable version for now. I might open another issue if I find another one in blender-v4 branch
