For the error that mentions the Windows PIN and Hyper-V, turn off PIN and password sign-in. Next, turn virtualization off in your BIOS, execute the guide's PowerShell lines and turn it on again. A request to enable VT-X / AMD-V asks for the opposite, and AMD boards usually call that setting SVM mode. The "disable secure boot" message goes away once Secure Boot is off.
The "all antiviruses are disabled" warning means another antivirus is still on the system or real-time protection is running. Remove the first and switch off the second together with SmartScreen. On Windows 11 the Turn_ON and Turn_OFF reg files from the guide help: launch them in turn, rebooting after each.
"Failed to map memory" hints at too little RAM; the build wants at minimum 12 GB. Clean out startup and reboot, and if the error sticks, go over autostart with AutoRuns. If the sticks add up to under 12 GB, or the "AES instruction set" error shows up, there is no fix, and the vendor suggests a refund.
Loader gone without a word? The library pack is missing. Menu on screen, but clicks fall through to the game or it only opens on the second try? Run Steam without admin rights, keep NVIDIA or AMD as the only overlay, turn off the EA App overlay. Radeon owners sometimes hit an AMD library error: fresh libraries usually cure it, and failing that, replace the DLL inside AMD Software following the guide.
Menu gone after a playtest patch? The build is away for an update and the product status will say so; in the meantime, have Steam check the integrity of the game files. If a blue screen hits you mid-raid, or a ban does, write to the procheat support chat: the vendor has a form for such cases, and we will help you with it.
