I cannot start the game from version v1.6.0-pre058_mc1.20.1 to version LittleTiles_ALPHA_v1.6.0-pre060_mc1.20.1

For some reason, I had to use the old version of rubidium, Because the Oculus light shadow loader relies on it (Rubidium 0.6.5)

Here are the errors:

Rubidium 0.6.5 is not supported anymore, you will have to use the newer version. Oculus cannot be used at the moment. Sorry there is nothing I can do about it. You will have to wait until it updates.
