I did a recipe in my modpack for an angel ring and it needs glass, but I tried everything and don't know how to write the script so it works with every glass type. I tried .withTag,but it just puts a tag on the item. Can someone help?

You are confusing NBT Tags with Tags. NBT Tags hold information on specific items, like how damaged it is, while Tags are used to group items (what you want).

Hold a piece of glass in your hand, use /ct hand, it should give you information on the item, such as what Item Tags it is in, so just click the one you want, and use that in the recipe instead of <item:minecraft:glass>, it may be: <tag:items:minecraft:glass>, but I'm not sure, best to see what the game says.
