Missing Twinmotion Materials

I made a archviz project using TwinmotiontoUnreal plugin about 6 months ago

but Today, I opened the project and All twinmotion materials are missing.

So I tried to reinstall the plugin but the problem still happen.

I don’t know why because I checked the plugin is enabled, and It has contents and materials in plugin folder

I guess it’s because of wrong path, but can’t find out how to fix this.

Does anyone know about this problem?

You seem to be missing the master materials:
can you see those 2 in your content folder?
