I see. No I doubt creating the folder or using someone else's would work sadly.
If you haven't tried killing off running apps (especially GPU-tuner related apps as they often have overlays in them), I'd try that.
You may try contacting EA directly here: Perhaps they have a better idea than me.

If you are looking for some more things to try, replace "Garden Warfare" with a game like Battlefield or Battlefront as they use the same engine and often can have similar errors and fixes. I don't want to just start throwing completely off the wall things at you to try but if you are desperate and looking for something to try.... google should return lots of results for those games not launching than it does for GW2 due to them being much larger player base games.

I doubt you would like this idea... but I'll throw it out there. You could partition your hard drive to make a bit of room for Win10, sign up for a free trial from Microsoft's website. Dual-boot the PC 7+10. You can reset the trial completely legally twice, so it'll last a good long while... I know dirty idea but win10 does install quick and with some tweaks like ClassicShell/Start and gutting the consumer apps.. I like it.
Sorry I couldn't be of more help.
Best of luck.
Having looked it up way further, I found an exact same issue, but for Sims 4. Seems like it's a problem with KERNELBASE.DLL, and the safest ways to fix it didn't work. And with downloading it off a dll site out of the question, I guess i'm forced to just uninstall a bunch of games and then use my Windows 10 reservation (which I really don't want to; I've broken my drivers AND crashed an entire harddrive by using Windows 10 as intended.)
Thanks for the help anyways, I'll probably say if it worked or if it's a lost cause.
Run game from file location
Sadly I don't recall what I did to fix it. But given my issue was with a Windows .dll file, I assume running System File Checker may fix it. I've also heard that making a new user profile on Windows can fix it as well.
