Community report notes
Sifu starts loading and KytyPS5 successfully initializes graphics, compiles multiple compute, vertex and pixel shaders, and starts/stops several AvPlayer videos.
ATRAC9 audio decoding is also initialized.
After compiling additional shaders, the emulator crashes on RenderThread 1 with an unhandled host exception / access violation.
The final error is:
Unhandled host exception: type=1 code=3221225477 pc=0x00000009050191b5 access=2 address=0x000000207d332400
Reported from:
src/loader/runtimeLinker.cpp:843
At the time of the crash, the shader counters were:
VS 11 | PS 11 | CS 37 | GS 0 | LS 0 | HS 0 | TES 0

Steps to reproduce the result Launch KytyPS5. Boot Sifu (PPSA03001). Wait for the game to initialize. Several videos/shaders are processed. Emulator crashes on RenderThread 1 with an unhandled host exception.
