When using the B4A ADB Manager (Tools/Run AVD Manager)
You must know that the Android Emulator Hypervisor Driver (AEHD) replaces Intel Hardware Accelerated Execution Manager (HAXM) starting with SDK version 33. (C:\Android\platforms\android-33\android.jar)
"Starting with emulator 33.x.x.x, HAXM was no longer available, as Intel discontinued development of HAXM. The Android Emulator Hypervisor Driver (AEHD) replaces Intel HAXM on Intel processors." Source: https://developer.android.com/studio/run/emulator-acceleration
You can download AEHD from https://github.com/google/android-emulator-hypervisor-driver/releases and you must unzip it and simply run the "silent_install.bat" file as Administrator.
