4.21 to 4.22 - translucent materials are black

Hi to all!

In the transition from 4.21 to 4.22 there was a problem with translucent materials. They become black. We found a funny solution:
If you have go to the Content Browser in the folder with the materials, the problem goes away before restarting the editor. However, in game mode or when recording cinematics, the problem remains.
Any help or advice is welcome.
