Just equipped a pair of stone daggers and now it is fixed very odd
I saw an update installed on the PS4, I hope it included a bug fix for this issue. I’ll test it and report back…
Tried that, no luck
Same issue with me, I was about to make a whole topic but glad to see it quickly. Anyways it was a very random thing for me. I was playing fine last night, then suddenly this morning when I went to find more thrall I realized I couldn’t equip my right hand items. I went through the list of suggestions and the hotfix that worked for me was to take off the bracelet by my bed. Was about to close out game too and wait for official solution but I’m glad it didn’t get to that. I have a personal feeling though the glitch is caused by an animation problem, because Everytime I tried he would start the equip and immediatly start the unequip animations. Also it did make all emotes unusable for me as well. Try researching the animation script for equipping, might just find a solution. Very odd it only happens in multiplayer though.
This had happened to my brother and I. He didn’t play for a week when it happened and during said week I had the same issue. Equipping a bow seemed to work for both of us as you hold it in your left hand. Try that, shoot some arrows for good measure
The latest PS4 update did not address the issue; still have it… 
I am also having an issue with this bug. I tried a dozen actions before recreating my character. It has happened again now, just two days later, and I am not going to recreate my character again. This really sucks. Both times I was working on building for a long period and when I went back to my pick to mine, I could not equip it or anything else in my right hand only. Also, I think both times the moderator switched our server from PVE to PVP. This is trash.
