CS:GO Workshop - Failed to publish file!

[Sathor]

My second entry to this forums, but this is a question. I just presented my project, de_investment

After another playtest yesterday evening with 10-14 players I decided to release it as an "alpha" version on the Workshop, but I get the error "Failed to publish file".

All models and materials are in the BSP, but not the NAV file. The map worked for everyone who downloaded it manually for the playtest.

I tried to publish a simpler map on the Workshop a few minutes ago, which I had created quickly, and that worked too (500 KB).

My map is 190 MB currently, which is within the 200 MB limit.

I tried to publish the BSP without the materials and models (56 MB), but that failed too.

I am running out of ideas!
