PS5 version does not allow characters to equip weapons/gear when meeting stat requirements from bonuses.
For example, a weapon that gives you +1 Strength and gloves that require 11 strength. Equipping the sword does not allow you to equip the gloves.
Using the same sword and gloves and removing all other gear, I I was able to equip the gloves on the PS4 version, but I can't do it on the PS5 version.
Characters can learn skills with augmented stats but unless your character naturally has the required stats, you can't equip weapons/armor.
