Is there a way to fix the skin second layer issue?

As far as I know, the issue is happening because the latest resource pack is meant to be used for 26.1, which has likely been the cause for my skin's second layer to disappear as well as everyone else's. I'm not sure if there is a way to "downgrade" said resource pack and only have the 1.21.11 one used, but I'm hoping something might be sorted in time for Fruma's release...

 

Not only does it remove the second layer, it also switches you back to being right-handed (if you're someone who likes your left hand to be the main one :') ). I wonder if switching game versions might do anything to help..? maybe..?
Unfortunately I'm not smart enough to come up with and actual fix, but for me, just switching the main hand setting back and forth fixes it for a bit :')) sometimes it'll eventually fix itself after a good few seconds too.
