Description
Describe the bug
When loading the map ge20 from the Portal mod, Gamma Energy, after converting it to the Portal: RTX format, the bridge attempts to dereference a null pointer.
How do you reproduce the bug?
Download the Portal mod, Gamma Energy. Modify gameinfo.txt to look like the attachment. Decompile each map with BSPSource 1.4.7. Recompile each map using the VBSP, VVIS, and VRAD executables from Portal: RTX. Launch Gamma Energy with RTX. Open the developer console. Type "map ge20" into the console.
What is the expected behavior?
The runtime should handle the map correctly instead of dereferencing a null pointer.

Research direction
Start by reproducing the crash with the Gamma Energy map ge20 using the attached gameinfo.txt and the Portal: RTX VBSP, VVIS, and VRAD executables. Inspect bridge32.log, bridge64.log, remix-dxvk.log, and the crash dump to locate the null dereference. Done means the runtime loads ge20 without dereferencing a null pointer.
