When publishing vehicles 'Workshop upload failed: "failure" (Error Code 2)'

[ActionedPlayer]

Hello,

since last week, I'm no more able to publish new or update any of my vehicles.
I've searched the web and found these solutions I tried without sucess:

- Adding my user to the security tab in my Steam games installation folder
- Adding my user to the security tab in my installation folder of steam
- Checking whether the thumbnail size is too big
- Checking whether the vehicle file size is too big
- Reinstalling steam and trying again
- Reinstalling Brick Rigs and trying again
- Changing the Steam download server
- Checking if my internet connection could be too slow (which it's not)
- Checking whether I have packet loss (which I haven't too)
- Installing Brick Rigs on my main ssd, on which my Windows is installed

EDIT: The workshop_log.txt, located in the log folder of my steam installation tells me:

[2018-04-16 13:33:24] [AppID 552100] Upload starting for workshop item 1122301359 by AppID 552100
[2018-04-16 13:33:25] [AppID 552100] Upload workshop item failed, failed build workshop depot 552100

I'd be very happy when someone could give me more ideas of what else I could do or
the solution itself.

My installation setup:
Steam is installed on my SSD ("C:") and all my games are installed on my 3TB hard drive ("Z:").

Thanks in advance!

I do know code 25 sometimes means your thumbnail is oversize
