How did you do that? I don't believe uassets from newer versions can be migrated to older versions, at least in my experience. The respective folders would just appear empty in the older engine.
Hi ! Sorry for the late reply, I simply didn't see the notification!
I have made a mistake, it was the other way around (the UE5 version came from the 4.27), sorry to bring bad news this late.
Hope you have found a workaround !
