New Core and 7.6 Fibaro RGBW do not work

After upgrading (2022-04-06) to the latest kernel and version 7.6, all fibaro RGBWs stop responding to commands. The units are connected from a Fibaro Home Center 3. They are included under entities and there they appear to be in operation. Anyone have a solution to the problem or know why?
