Problem with uploading a custom map to Steam Workshop

[Havel]

Hello.

I’ve been tried to figure this out for few days already, but cannot find the problem… So i thought to ask some help!
The error i get DW_MUS_MainMenu which is something to do with the mainmenu music i assume, but why would that be the problem/error?
When trying to upload to Workshop, i get this :

SDK Frontend started 21.4.2019 23.11.13…
WSTOOL: Initializing Steam client
Steam API initialized
Waiting for Steam task to finish.
If you’re new to the SDK frontend, please read …
Quick start:

• Make sure Steam is running on the account you want to upload to the Workshop with!
• If you have an existing Workshop item you’d like to import, use “Existing Workshop Item”
• Otherwise, to create a new item click “New Workshop Item” and give it a name
• You’ll then want to add at least one map or script package (if you’re making a mod) to build
• If you’re making a map that can be played on Chivalry without any mods, be sure to leave “Base Chivalry-compatible map(s)” selected
• Fill in the Workshop title, description, and preview image path
• Press Start
• Once it’s done, your item should be in the Workshop, but set to Private so only you can see it until you’re ready
• To access maps in-game right now, use the open command in the console. e.g. “open aoctd-mymap”
  No scripts selected; nothing to compile.
