EA Anticheat preventing launch on PC

After not touching the game for a few days, I try to relaunch the game again but get stuck on the loading screen saying "Starting Javelin Anti-Cheat..." before being greeted with the error message:

"EA Javelin Anticheat encountered an error. Please restart your PC.: C/Program Files/EA/AC/EAAntiCheat.GameService.exe (7) (2)"

I have tried a wide variety of changes over two days, including restarting my pc as well as deleting and reinstalling both the EA app and the Anticheat itself to no avail. Looking at Task Manager during launch, the Anti Cheat appears to be trying to work, using up CPU, before randomly dropping back down to 0% with no changes in the loading process.

I do believe the problem may be that the game files for EAFC 26 are on a different disk (E) to the one mentioned by the error message (C). However, this has never been a problem up until now, with that same disk (E) also having anticheat on. I have installed and repaired the anticheat on the E disk, the installer cannot identify the anticheat on the C file. Could it be possible these are interfering with each other? I have tried just deleting the files from C, but this just makes me reinstall them in the same place upon launch of FC 26.

Again, as mentioned, this is a completely new problem for me that has seemingly happened out of nothing. Any help with this would be greatly appreciated.
