Trouble opening Apex after new season

After updating the game on steam after the release of the new season, I was obviously eager to try all the new stuff so went to launch the game. As usual, an Easy Anti Cheat loading bar pop up thing appears on my screen, but for some reason it still displays the screen from last season (with conduit on it, and colours from last season) and after a while, rather than opening the game, another easy anticheat popup comes up saying:

Untrusted system file (\?\GLOBALROOT\Device\HarddiskVolume3\Windows\System32\bcmihvsrv64.dlll)

I’ve tried uninstalling and reinstalling the game, updating graphics drivers, and searching online for anyone having the same issue, and have not yet found any solutions. Anyone know what to do?
