Failed to Upload MOD to Workshop

[STH-SKYLIGHT]

• My issue happened while using mods.

What happened?

I am consistently encountering failures when attempting to upload a MOD to the Steam Workshop. The process gets stuck at the "Submitting item to the Workshop" stage. Despite multiple attempts—including restarting the application, switching networks, and reinstalling the game—the issue persists.

Specifically, I am able to create and upload new small MODs without any problems. However, I cannot update older MODs that have already been published. Additionally, for the MOD named "SET BurningAsh," I attempted to resolve the issue by deleting the workshopid from the filelist in order to republish it, but the upload still fails every time.As shown in the attached screenshot.

This issue is exclusively occurring in Barotrauma and has been persistently happening over the past two days. I am unsure whether it is caused by a Steam connection problem or an issue with Barotrauma itself.
I would like to understand what might be causing this problem and how it can be resolved. Any guidance or support would be greatly appreciated.

Besides:If the issue is caused by specific content within a particular MOD, please let me know.

Thank you.

Open steam console steam://open/console and try to publish, will it say anything funny?
Current mod version is

Are you trying to publish it as 0.1? Mb that's what steam doesn't like

• Can confirm workshop updater has magically stopped working in the "Autumn update".
• Tried the current 'winter' unstable build too, no luck.

Could not trigger this--uploading, updating, etc, all succeeded on my end.
