There is no "official" patch, but modders have made significant breakthroughs:

Find your MKKE installation folder (usually Steam\steamapps\common\MKKE ).

This usually happens if an asset file is misplaced or corrupted during extraction. Double-check that all .XXX files were placed in the correct directory. If the crash persists, restore your backup files and try the installation again.

Paste them into the DiscContentPC\Asset folder inside your main game directory. Select when prompted. Step 4: Update the Character Select Matrix

Modern mods use custom DLC managers and script injectors to "unlock" or port the PS3 assets into the PC environment.

Mortal Kombat Komplete Edition is an older title and rarely receives official updates, meaning your mod is highly unlikely to be broken by an official patch. However, using poorly optimized or outdated versions of the mod can cause the game to crash during specific animations, such as transitioning into a Fatality or loading specific arenas. Ensure you read the comment sections on modding forums to find the most stable, up-to-date version of the script. Conclusion
