TOPIC: GMod freezes at "Workshop Complete" when joining.

The title is pretty self-explainatory.
After downloading the content from the workshop, I clicked the join button and everything went fine until the end, when it says "workshop complete". At that point, the game itself freezes which forces me to alt-tab and close it via task manager. Waiting is not a solution, sadly.
The odd thing is how this glitch/bug/error only seems to trigger when I join ZARP's #1 DarkRP server.
I haven't tried on #2 because I don't like rockford as a map, but I will test if you think it can help in any way.
After scrounging through the internet, I tried every possible solution - from reinstalling the game to disabling all addons etc. - but nothing worked.
I read that completely re-installing windows might solve it, but I seriously hope that's not the only way. My god-awful internet speed combined with my 142 Gb of stuff in my computer would end up taking days for the thing to finish.

-noworkshop
Should allow you to disable to workshop system, try using that and see if you can join.

Adding -noworkshop to the launch options did not work.

try cl_downloadfilter none

Instead of freezing at "Workshop Complete" it now freezes at "Retrieving Server Info".

How long do you wait?

On s3 my game used to freze on downloading map.

Disable all your addons and clear your downloads then try join. Alternatively you can reinstall gmod and then try join with workshop disabled.
