Characters disappear in the Inspector.

unity2022.2.0b TMP3.2.0-pre.4

I recently updated my project from 2019LTS.
After that, the characters entered in “string” or “TextArea” in the inspector disappeared.

Now, I get one of the following error messages:
1: NullReferenceException: Object reference not set to an instance of an object.
2: MissingReferenceException: The variable m_AtlasTextures of FontAsset doesn’t exist anymore.

My language is Japanese.
I know I get similar errors when the TMP textures are full, but I don’t use TMP for my project.
It can be fixed by restarting Unity, but it is troublesome because it happens frequently. Anyone know how to deal with this?

Here is the log.
