"Download Workshop Items" on each start of rFactor 2

Since a few days I have a problem when I startup rFactor 2. Each time I get a popup "Downloading Workshop Items" from the rFactor 2 Launcher and it says '2 items remaining'. But nothing is happening and Steam is showing no downloads. When I close the popup via the X, rFactor 2 is started. I already tried reinstalling rFactor 2, but that did not solve this issue. Btw, I have 117 subscribed items in the Steam Workshop.

 

One of them has been deleted, check wich one and delete subscription to it.

 

How can I find out which one was deleted? Checking 117 items one by one is quite time consuming.

 

I know but I think you have to check them one by one, Steam workshop isn't really handy for such problems...
When I had the same issue was the Celica Gto, there were 2 versions of it, one was deleted...maybe this can help.

 

Yes, that Celica GTO was also in my subscribed items. I unsubscribed it and now it's saying only '1 item remaining'. I will keep searching for the 2nd one! Thanks!

 

The 2nd one was 'SRVN IndyCar 2016-I'. I unsubscribed and now the message is gone. Problem solved!

 

I have different problem. After running rf2, first steam downloads some content, then I got window that says Downloading Workshop Items, but nothing happens. I can close it and it looks like it's downloaded but I'm not sure.
