I stopped being able to equip accessories when I updated to 0.3.7.0
The problem has persisted across all 3 computers I’ve played TU on. Reinstalling did not fix it, verification did not fix it. I can access the accessories menu, but clicking on accessories does nothing, and there is no pressing animation. I can’t find anything I did besides updating that triggered this happening.
The issue also occurs in minigolf, in which I cannot equip any hats.
I would also try turning off Steam Cloud, deleting the Steam\steamapps\common\Tower Unite\Tower\ClientPlayerData2 folder, and then launching the game. Doing that has fixed some issues with broken UI in the hotbar, but given that the folder also contains a file called “Wearables.dat”, it could possibly also solve your accessory problem.
Of course, if it does fix your issue, you can turn Steam Cloud back on.
Not sure if this is a problem for some and sorry for beating the horse but what I use to fix the problem isn’t a permanent solution but if you have the size potions just equip one and take it off. You should be then able to use your items. You can also press K and respawn.
