Game Not Launching

I hit the launch button, the game launches, then instantly crashes. I have fully updated my NET packages, the error log suggests it is due to a lack of the _BE.exe file, but that file is deleted by the patching process of the launcher. If it is trying to look for it in my main EFT folder I do not know why it cannot find it as it is most certainly there and on the same drive.

I will post in addendum that I used the Installer.

Retrying without the installer, and after purging all files related to SPT beforehand (saw it could be related to installing over an old install, which I didn't think I did but was worth checking), has the same problem

I completely purged all files related to EFT on my computer, and redownloaded and reinstalled the game, then used the installer again. The game now launches.
