Forge crashing when loading any mods - Minecraft 1.21

[Captainuseless22]

I have tried downloading forge and installing mods on my own, and it lead to crashes on start up. I have tried installing mods through curseforge to the same effect. I tried virtually every installation of forge that's available for 1.21, from forge 51.0.1-51.0.24. Either the game crashes when trying to load mods, or the game does not read the mods in my mod folder and runs like it was vanilla. I do not know what is causing the game to fail to recognize the mods. I installed forge from curseforge, and added the mods directly from cursed forge, and all of the mods are 1.21 compatible. in spite of that, it is still failing to load mods. what else could I do to get this fixed?

the error loading the mods is "Error loading mods, 2 errors have occurred during loading" with each saying "Invalid mod file found." here is the crash log:

[TileEntity]

Remove mahoutsukai and waystones

[Captainuseless22]

ok, but this still happens with virtually every mod that I install. otherwise I am effectively playing vanilla

[TileEntity]

Make a test with a pre-configured modpack on curseforge - use such a modpack as working base

[Captainuseless22]

ok, I downloaded "Slightly flavored" 1.21 and interestingly, way stones was included and worked without issue. I took a look, and the most recent version of it released was for 1.20, so I think it gave that version priority over the 1.21 version. I was curious, and looked into mahou Tsukai, and saw it had the same thing on its page. though when I tried manually installing the 1.21 versions, it still crashed on loading. I'm not sure why Waystones wasnt working previously, but I guess that issue is fixed, so its fine. I don't know why mahou is labeled as 1.21 if it crashes every time, but thats an issue with the mod creator then. I'll just have to wait for a new release

[TileEntity]

With picking mods, select the filter for the version and the Mod Loader

With 1.21 most mods will be available for Forge and NeoForge

So is you are using the Forge Mod Loader, do not add NeoForge mods
