Unable to upload (Error 13)

I’m unable to upload anything, I keep getting Error 13. I tried .blend and .obj files, which is what I’ve always used.

It’s not a problem with the model, because I saved the default blender cube and tried to upload it and it also gave me error 13. Then I tried uploading a model that I had already uploaded, so I know it works and I got the same issue.

I had a similar problem, I solved removing textures. Eventually, I came across a texture that was messing with me. This is my case.

It seems the error was a lie and the models did upload, for some reason. I’m not sure what coudve happened
