Research direction

Start by reproducing the launch on Windows and Linux, then inspect bridge32.log, bridge64.log, remix-dxvk.log, and NvRemixBridge.exe_20250805_234756.dmp.log for the failure point. Compare the behavior with the reported remix-main+15f604aa version; done means HL2 RTX and Portal RTX start without crashing or hanging.
