How do you proceed?

well, like any other person. i write the title, the description, then the thumbnail. afterwards i check the boxes for the necessary options. then a set the the addon to private so i can edit it for the referance images. then i press publish. afterwards, it crashes not even 3 seconds later.

Hello, are you trying to upload something to the workshop using the mod manager?
Is the mod manager crashing, and is the upload failing?

If so, try this:

There is a workshop upload limit of 2 GB. The workshop will crash if your mod is larger than this.

There are two folders when you open the Half-Life: Alyx folder: a. content
b. game.
In the content folder, you'll find your mod and all the original resources like pictures and models.

In the game folder, there is a compiled version of your mod. The editor automatically generates this folder while you are working on your mod.

I usually solve upload errors as I describe below. But always remember to do backups! BACKUP, BACKUP, BACKUP!

Inside the game folder, there is a maps folder. I usually delete all the content inside the maps folder.

After that, I compile only the map I’m going to upload to the workshop.

I don’t know why, but the upload always works after I do this. If it's still not working, then back up your map save files in the content folder and leave only your last save in the maps folder.

If that doesn't work, create a new mod and copy your old mod into the new one. Then, use only your last save file for your map.

All I know is that when the workshop manager crashes, it’s either because of something in the maps folder in the game folder or because the mod is too big.

the thing is, i'm trying to upload a rigged model, not a map.
