Dell mobile connect drivers failed to load, #2

Hi. I bought Dell G7 on may this year, when I see first time Dell Mobile Connect it worked very well. I did calls and answered calls. But after 1-2 month the Mobile Connect software suddenly did not show calls and other noifications.. 

There was notification about failed loading dell mobile connect drivers. 

Untill this day I cant find any solving this problem on internet.. 

Problem only on drivers on PC.. No problems with phone.. 

Please help me Dell support center.

Thanks in advance.
