Description
When accepting a Remote Play Together invite from another user, the streaming_client process immediately crashes with SIGSEGV. Hosting Remote Play works fine. The crash happens every time without exception.

Stack trace
The crash always occurs at the same location:
#0 eglGetDisplay (gameoverlayrenderer.so + 0x4d994)
#1 libSDL3.so.0 + 0x2797fe
Called from streaming_client with the -steam-overlay flag

The streaming_client is launched with -steam-overlay hardcoded in its arguments regardless of the "Enable Steam Overlay" setting in Steam preferences. gameoverlayrenderer.so then calls eglGetDisplay via SDL3, which crashes.

What I tried

• Disabling Steam overlay in settings (has no effect, -steam-overlay flag is still passed to streaming_client)
• Removing libnvidia-egl-wayland2 from the EGL stack (crash persists, moves to Mesa EGL path)
• Removing all Nvidia EGL vendor configs (crash persists at same offset in gameoverlayrenderer.so)
• STEAM_GAMEOVERLAYRENDERER_DISABLED=1 env var (has no effect on streaming_client subprocess)

Expected behavior
Accepting a Remote Play Together invite should connect me to the session.

Actual behavior
streaming_client crashes instantly with SIGSEGV every time.
