Technical Error on every screen on 6.3

Hi !
I just updated from 6.2.5 to 6.3, and there is a major issue that make projeqtor unusable :
Each time I try to access an element form (example, when I try to open a risk), I got a technical error.
Nothing in log...



Do you already know this issue ?

And of course, I checked network before, everything is ok...
Just in case it can't be solved soon, is it possible to revert to 6.2.5 without errors ?

Here is the browser log :
