i had the same issue/solution. the support is an absolute joke so don't even bother.
after some troubleshooting i did realize that FaceIT anti-cheat completely breaks the BH tools. this could be the case for other anti cheats (val, cs2, etc.)
i uninstalled faceit anti cheat and got SOME menu functionality (the auto-greener does not work at all, the MC takeover / stamina toggles also do not work).
even if you think the anti-cheat wouldn't have any effect on your game, it will.
Step 1. Disable Windows Defender / Uninstall any anti-cheat
Step 2. Extract Loginmenu, Run Loginmenu as Admin
Step 3. in the command console enter 1 or 2 (just the number)
Step 4. Once menu opens, enter key
Step 5. Launch 2k. A "Game Detected" notification should pop up in the bottom righthand corner
