I can't currently upload a mod file

Hi, I noticed that I am currently unable to upload a new file to my mod The Endless Hordes. I can edit the mod's page and I can remove files, but whenever I try to upload a new file, it says starting upload, then it jumps through a progress bar, then it goes back to saying starting upload with the progress bar frozen at whatever percentage it would have been at before the jump to 100% (it tends to jump 25-45% at a time), then the progress bar disappears entirely, but the upload file button is still there, with the file name displayed next to it.

I do not have five files uploaded on that mod's page (currently only 3), so it shouldn't be a file count limit.

The new file size is 6.something mb, and the total combined size of the currently uploaded mod files and the new one would still be below the 20 mb limit.

I have tried restarting my computer.

I was able to upload mod files just fine yesterday.

I was wondering if there is just a bug on the website currently, or if it is something on my end? I did just update to Windows 11 this morning, so I'm not sure if that would be causing problems, or if there might be a setting change or something that would be causing problems.

Also, I did a little more testing and tried uploading the file of one of my other, smaller, mods (I would have removed it if it uploaded successfully), and it had pretty similar results.

And I was able to upload the main mod file to curseforge successfully, so I know it isn't a problem with that file on its own, or a problem with uploads in general from my computer.

Does anyone know why this is happening and how to fix it?
