Fixing missing runtime environments in Fortnite

When the crashes started hitting during build fights, I thought my RAM was unstable. However, GPU-Z showed core clocks steady at 2430MHz - 2660MHz and VRAM temps between 71℃ - 77℃, so the hardware was rock steady. After failing with three different driver combos, I realized the DLL dependency chain was snapped. Instead of a simple reboot, I fired up the Command Prompt as admin and ran the system image repair tool; the logs were filled with corrupted files being replaced. Once finished, that annoying 3-5 second hang on the loading screen vanished, and build commands felt snappy again. One annoying detail: the fix wiped some of my hotkey mappings, forcing me to manually edit the registry to get them back. After three match cycles, no more runtime errors. It was a total grind, but I can finally crank towers without the game folding.
