Howdy teddolek1, thank you for posting your question and welcome to the Unreal community.
I have encountered this recently as well. After retargeting a UE4 skeleton and anims to UE5, I noticed the RootMotion was not working either. I found a neat thread that gives credit to this YouTube video. I tried it for myself and it solved the problem I was having on my end too.
Credit to muchogrande for finding this video and kudos to Teella Blood for making it.
