How To Fix Meccha Chameleon Crashing And Freezing
How To Fix Meccha Chameleon Crashing And Freezing On PC Meccha Chameleon crashes and freezes on Windows because its Unreal Engine 5 build fails to decompress shaders with Oodle, most often on 13th and 14th Gen Intel CPUs, alongside corrupted game files, outdated GPU drivers, and missing Visual C++ runtimes. It shows up as a crash on launch, a black screen that freezes the whole PC, a "LowLevelFatalError" or "An Unreal Process Has Crashed: UE-Chameleon" message, or the game freezing mid match. Forcing DirectX 11, repairing the files, and updating your drivers clears it, so the game boots to the menu and holds steady through a full match.
STEPS
Step 1) Add the DirectX 11 launch option in Steam (Properties, General, Launch Options): -dx11
Step 2) In Properties, Installed Files, Browse, set the game's main .exe to Disable fullscreen optimizations and Run as administrator (Compatibility tab)
Step 3) Verify integrity of game files (Properties, Installed Files)
Step 4) Update your graphics driver from your card maker: https://www.nvidia.com/download/index...
Step 5) Fully exit Steam from the system tray, then relaunch to pull the latest game patch
Step 6) Delete everything inside the Steam appcache folder
Step 7) Install the latest Microsoft Visual C++ Redistributables, x64 and x86: https://aka.ms/vc14/vc_redist.x64.exe
Step 8) Turn off Steam, Discord, and GPU overlays and close background apps (for freezing mid match)
Step 9) 13th or 14th Gen Intel only: update your motherboard BIOS
