Gena Editor Error (EnsureRunningOnMainThread) on scene startup

[chiken]

In Unity 2021.3.18f1, if you have multiple scenes that use gena and switch between them in the editor, a unity error shows up in the editor.

It doesn't seem to be a specific 2021 LTS version issue as I had this issue with the older 2021 LTS versions like 2021.3.13f1, but I didn't report this bug last time since I skipped upgrading gena due to this bug.

Gena Pro ver 3.4.7

To reproduce this issue.

Ensure you have two scenes that uses Gena.

Method 1

1) Start Unity with the scene A already loaded that has Gena.

The error shows up

Method 2

1) When scene A is loaded in the unity editor, load scene B into the editor by double clicking it.

The same error shows up here.
