💡 Quick Answer & TL;DR
If you are trying to play the PC Open Beta of Marvel Tōkon: Fighting Souls and are hit with the marvel tokon error d0000207, it is a conflict with your PC’s security settings and Sony’s aggressive anti-cheat configuration.
- The Core Issue: Your Windows “Core Isolation/Memory Integrity” settings or gaming software drivers (specifically WinRing0x64) are blocking the game’s launch.
- The Fastest Fix: Open Command Prompt as Administrator, type
sc stop WinRing0x64, hit Enter, and launch the game again. - Windows Compatibility: Despite minimum specs stating Windows 11 is required, many users are successfully running the game on Windows 10 after applying this fix.
The highly anticipated open beta for Marvel Tōkon: Fighting Souls—the new crossover fighting game by PlayStation Studios, Arc System Works, and Marvel Games—has finally arrived on Steam. However, PC gamers are running into a brick wall before they can even throw a punch.
The marvel tokon error d0000207 has become the most widely reported crash on day one. This error prevents the game from launching and is heavily tied to Sony’s strict backend security and PSN integration on PC. Fortunately, there are reliable workarounds that don’t require upgrading to Windows 11.
🔍 Why Does Error D0000207 Happen?
This error isn’t a problem with your graphics card or RAM; it’s a software conflict. Here is exactly what is triggering the D0000207 code when you hit “Play”:
- •Anti-Cheat and Core Isolation: Marvel Tōkon requires high-level system permissions to prevent cheating. If you have “Memory Integrity” enabled in Windows Security, it blocks the game’s driver from loading.
- •Conflicting Gaming Software: Background software that monitors CPU temps or controls RGB lighting (which often use the
WinRing0x64orWinRing0_1_2_0services) are flagged as incompatible by the game’s security. - •Secure Boot Status: Some users experience the crash if their BIOS does not have Secure Boot enabled, though this is less common than the Core Isolation issue.

🛠️ Step-by-Step Fixes for Error D0000207
Follow these steps to bypass the error and get into the game. You do not need to upgrade to Windows 11 to make this work.
Fix 1: Stop the WinRing0x64 Service
This is the most common fix shared by the community on Reddit and Steam discussions.
- Type cmd into your Windows search bar.
- Right-click Command Prompt and select Run as administrator.
- Type the following command exactly:
sc stop WinRing0x64 - Press Enter. Once it says the service is stopped, launch Marvel Tōkon again.
Fix 2: Review Memory Integrity Drivers
If the command prompt trick didn’t work, Windows Security might be actively blocking the game.
- Open your Windows Start Menu and search for Core Isolation.
- Under Memory Integrity, look for a button that says Review incompatible drivers.
- Click it to see a list of conflicting
.sysfiles (often related to old mouse/keyboard software or RGB controllers). - You will need to manually uninstall or delete the software attached to those conflicting drivers to allow the game to boot.
⚠️ The Next Hurdle: The Infinite PSN Login Loop
Many players report that immediately after fixing Error D0000207, they are met with a new disaster: an infinite PlayStation Network (PSN) sign-in loop. You might get a “Network Error” despite having a perfect connection, or the game will continually prompt you to log in.
How to bypass the loop: According to community testing, logging in manually using your email and password frequently fails. Instead, choose the QR Code Login option on the screen and scan it with your phone. If that still results in a Network Error, try using a VPN; some players have found success bypassing regional server locks this way.
