Unable to use MillionDance due to Unity version update (2020.3.32f1)

[KyanaProducer]

In MillionDance, it was found that some files were not available and the following error was output.

In searching for the cause of this error, we checked in AssetStudio and found that the Unity3D file version is 2020.3.32f1, and it seems that this version is probably not supported and the error is being output.

Incidentally, many of the recent Unity3D files in MLTD are this version, and it seems to be difficult to create models in MillionDance.
