Universal 10 game wont run if "internet client" capability selected

I have made a game (Attack of Monsters) that is in the store. It does not have the internet capability selected (you can see in the store page that i dont have that in capabilities). But it does have InApp purchases.

I thought for inapp purchases internet capabililty had to be selected.

Anyway i want to display ads in my game and i am using Windows Store Native asset. But when i turn on internet capability in my game, it wont run. the game window starts and it displays a grey screen and nothing else. tried in debug, release, master on a Win 10 PC with VS 2015 community edition. Using unity 5.3.4p5.

Can anyone let me know what could be the issue?

Just to let everyone know, this seems to be an issue with my computer only. took my project files and ran on a friends computer and it works fine.

So far i have turned firewall off, run unity and visual studio as administrator. but no help.

gonna reinstall visual studio now.
if that doesnt work, then i’ll reinstall windows 10.

will let you guys know either way. and if someone else has a solution do let me know.

Reinstalled VS, didnt fix it.
Re installing win 10 now
will keep you updated

Phew found where the problem was.
when i build the game from Unity version 5.3.4p5 the game wont run if internet capability is selected for Universal apps.
But when i build it using 5.3.4f1 it worked.

Should I file a bug report? Mods?

If you want, then yes, I probably would. I hate bugs so this could help other peoples problems.

For anyone who wishes to know:
After reinstalling windows the issue fixed itself. so i guess it wasnt a bug in unity or VS but in my system.
What exactly cause it i dont know.
