Hello!
Recently, when I try to start arma 3, I get this error code. He started doing this 2-3 months ago.
I tried every possible solution that I could find and that came to my mind.
Thank you in advance for your help.

I can't read that, but throwing it into google shows results.
And translating it into english "The cloud file provider is not running." will lead to even more results.
