Resource Packs don't load when switching versions

This happens when you switch versions, like when you switch between 1.19.3 and 1.19.4 the pack would not load until you reload it in-game by pressing F3+T. The pack was made for 1.19.4, so when you switch from 1.19.3 to 1.19.4 the pack unloads even if it shows in Selected Resource Packs
