MetaHumans Fingers are broken


MetaHumans fingers issue (The fingers are broken!)

I’m writing here after a huge research online, I didn’t find any solutions and the ones I did find weren’t helpful at all, please help.

The MetaHumans fingers are breaking after importing and retargeting “office animations” pack.
The office desk pack

I tried any solution I found online but nothing is working, that includes different retargeting bones order and anything you can think about.
I tried to fix the rotation of the fingers manually but it looks bad and at some point while the animation is running the fingers are twisting and breaking over and over again.

Here are some photos (once again I have tried many combinations but nothing works, please help):
