Problem with CBBE (The Elder Scrolls 5: Skyrim)

I bet on pure skyrim, only with skse, CBBE and instead of character models, some huge red rhombuses with an exclamation mark in the center. I tried to put together with different mods (Racemenu, FNIS, SkyUI, Demoniac textures, CBBE SMP Basic, HDT SMP, HDT Physics Extesions, Body slide), nothing helps, I put an unofficial patch, it also did not remove the problem. I thought to put UNP instead of CBBE, but UNP is a similar problem, the only thing is that there are fewer rhombuses, but everyone goes purple. Tell me what is the problem?
