Yes, it is a false positive (assuming you got it from here or Faerin).I restored all the files and the game loaded fine. They got quarantined due to low reputation, so I just assumed them to be false positives. This made me suspect they might be new.
Just strange that it should suddenly happen now, for the first time, with 0.7.1.
There were around 25-30 files that got removed & the game would launch to a black screen, but not even show the loading icon.
I noticed a few were associated to the videoplayer, have attached the Quarantine report.
That is a lot to whitelist, assuming that is even an option (ran into problems with that from aviria), if you can't, you might be able to extract it onto another device and copy it over, which will allow for whitelisting.
Depending on your antivirus, you might also want to consider an alternative.
You could also go into safe mode and extract it there.
