Open PowerShell as Administrator and type:

Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

If it says "State: Disabled," you are good to go.

After restarting, launch MSI App Player. Error 59300 should be gone.

| Scenario | Likely Cause | Best Fix | | :--- | :--- | :--- | | Error appears after Windows 11 update | VBS (Virtualization-based Security) enabled | Method 2 (Memory Integrity) | | You use Docker or WSL2 | Hyper-V forced on | Use BlueStacks Hyper-V Edition | | Error appears after playing Valorant or LoL | Riot Vanguard anti-cheat uses VBS | Disable Vanguard or disable Memory Integrity | | Laptop with NVIDIA/AMD GPU | Graphics driver conflict | Method 3 (Switch to DirectX renderer) | | Old CPU (Intel 2nd gen or older) | No VT-x support | Upgrade PC (emulation impossible) |

If you tried everything above and still see "Error 59300," your Windows installation likely has a corrupted Hyper-V kernel that refuses to release virtualization locks.

Solution: Perform a Windows 10/11 In-Place Upgrade.

Review Note: MSI App Player is essentially a "skinned" version of BlueStacks. Sometimes, the MSI version falls behind on updates, causing compatibility errors with newer Windows builds.
