Epic Store and neither ReShade nor ENB working

Hi, I noticed that if I try to add either ReShade or ENB to my Epic Store copy of this game I get an error pertaining the license, with a pop-up from epic telling me “Licence not verified - INIT of EOS has failed”

I found a lot of people on the internet with the same issue but apparently no workaround. I already contacted Epic Store support but they don’t seem to understand the problem.

Thanks in advance for any help.
