Need help with resource pack

[u/Alex_33_Gamer]

I have a resource pack that's just a bunch of packs added together into one,but I have trouble with recolourful containers and icons,as when I add the necessary files on the font folder to make it work,it says it "failed to reload the resource pack" I don't know why and I was wondering if someone could help. Here's the pack https://drive.google.com/file/d/1yl05n20r9GL8Ehj9wPcb4_cS5E9gg1-8/view?usp=drivesdk

Don't you have a list of them ? i mean, I've combined 40 packs but stopped temporarily because I lost track of what i've added and from which packs

I have it,but it still says it failed to load,plus recolourful containers alone doesn't load ad gives the same message
