[1.17.1] Issues with textures not appearing

[DavidQF555]

There are a lot of instances of this happening when I ported my mod from 1.16.5 to 1.17.1. One specific instance is this item. The textures somehow cannot be found and it is displayed with the purple and black squares. I'm also getting this error:

Even though the texture in question is at minecraft:textures/gui/bars.png, which should be there. I'm really confused as to why this is happening.

post full log, are you sure the texture is in the correct location and is named correctly

Logs. For the first case, I'm pretty sure. For the second case, it is a minecraft texture, not a modded one so I hope so.
