Getting Desperate for a fix. Dll error

So we all remeber the “failed to load launcher Dll” it got fixed, but recently it has occured again for me, sometimes i will not be able to even start garrys mod and if it does work… as soon as i join a server the error pops up again.

Ive gone to steam support and have got nothing and even tweeted garry. Please if anyone can find a fix or a way to get garrys attention i would be so greatful, please im getting desperate this has happened for a week i have a server to run and i dont want to lose it all.
