forge 1.21.11 resource pack incompatible error

UPDATE**
Dug into the logs and found the following highlighted lines attached with the line previous to them

[19:34:20] [main/INFO]:Launching target 'forge_client' with arguments [--version, forge-61.0.3, --gameDir, C:\Users\elija\curseforge\minecraft\Instances\eli, --assetsDir, C:\Users\elija\curseforge\minecraft\Install\assets, --uuid, redacted, --username, ogspiff25, --assetIndex, 29, --accessToken, **********, --clientId, 75d6e0-b2d1da-c68cbc-4308e0-5ff233, --xuid, redacted, --versionType, release, --width, 1024, --height, 768, --quickPlayPath, C:\Users\elija\curseforge\minecraft\Quickplay\8b0c5374-30de-49e4-b03c-5db345efb58c.json, , , ]

How could I fix this? Or is this an issue with the mod/resource pack dev?

forge 1.21.11 resource pack incompatible error

Hi, I'm new to the whole modding and forum side of things so I don't quite know the proper decorum, but I need some help figuring this issue out.

So I'm attempting to load a few resource packs through forge. (recently updated, v 61.0.3)
All resource packs have also been recently updated to match the current minecraft version, (1.21.11) and the forge profile is set to launch the game with the matching version.

With that said, no matter the resource pack, mod, or shader that I load, I'm running into the same problem. When I go to create a new world and go to the Data Packs tab, I see the forge resource packs in there, but they're greyed out.
On top of that, when I hover over the main forge resource pack, I get the same recurring message ; Incompatible (Made for a newer version of Minecraft)

I've uninstalled and redownloaded all the mods, CurseForge itself, and Minecraft all to no avail.

What am I missing? (ps. I can attach pics below if it helps to visualize the issue.)

ATM 10 + Dragons from Dragon survival / Failed to sync registries from the server:java.lang.NullPointerException error

When trying to connect to server I get Failed to sync registries from the server:java.lang.NullPointerException error. Here is Server log https://mclo.gs/I4v9PFa Here is Client Log https://mclo.gs/wlb7d1j. Please let me know if you need anymore information. My friend is hosting the server while i build the modpack. My goal is ATM10 but with players that can be dragons like the ones from Dragon survival. All I added was the dragon mods from Dragon survival and the paintings and updated the mods to run on the current version of atm10. Let me know if you need any more info.

Loading into certain worlds stuck on "Reading world data" then stops responding.(FIXED)

Try removing the file ars_additions/glyph_retaliate.toml from the config folder.
If it happens again, search the log for "Failed loading", and see if it comes up with any more files. Might be worth a try backing up/removing the whole config folder if it repeatedly happens.
