Metahuman face became my sleep paralysis demon when upgrading project from 5.2 to 5.3

Each time I enter UE5.3 editor, this is what welcomes me:

TBC, this started happen when I upgraded project from 5.2 to 5.3. This MH originally converted to v5.2 from v5.1 via MHC (in 5.0\5.1\5.2 it looked fine), BUT other metahumans, created earlier for 5.0 and 5.1 render correctly.

Btw, in-game, this mesh is also rendered correctly, but this editor bug is interesting. In BP viewport head looks normal, removing skeletal mesh and adding it back doesn’t help.

Only 5.0 and 5.1 considered as “legacy” MHs and allowed by MHC for conversion, so there is no way to convert it to 5.3, I think. Reimporting it from Bridge is a hell I no wanna consider, 'cause it’s takes so long.

Any ideas?

Update: clean install of MH - zero results, the cause, allegedly - the “PostProcessAnimBP”, disabling it - makes face mesh look somewhat fine… but ■■■■… those eyebrows “be edgie”… literally. In addition to clean install, other MHs started to look the same, like “in screenshot” the same…
