I had the same issue after the latest update but I did find a “fix” for it. I say “fix” because it requires using one of the latest experimental builds of UE4SS, which might also introduce bugs, so you have been warned.
I don’t know if direct linking or linking to where the experimental builds is allowed or not, but how you find them is this…
Go to UE4SS github page and click on the full installation guide link.
Under the Installation section, scroll down to Experimental Install and click the link found there.
Scroll down and under assets look for the latest build of UE4SS_v3.0.1-*.
I am currently using UE4SS_v3.0.1-54-g7f6d0c7 and so far it seems to be working ok, now we just need to wait for the patch to hit the main build and for the mods to be updated
