Cuphead freezes completely after my friend joins via Remote Play.

[Sirfi]

When my friend joins via Remote Play, the screen turns white, and the system prompts to close the game.

Below, I will send the crash log that I was able to obtain. Beforehand, I want to mention that I have already tried updating Steam, drivers, DirectX, and Visual C++, as well as verifying the integrity of the game files. I am also certain that my computer is capable of running Cuphead. This issue only occurs when my friend joins.

Damn, take it. There's a lot of it, and Steam doesn't allow me to send the full message. I hope what I sent is enough. If you need more information, let me know.

[Sirfi]

According to the crash log, Cuphead crashed with an "Access Violation (0xc0000005)" in the module gameoverlayrenderer64.dll at address 0033:ec994613.

That's the response ChatGPT gave me, but it doesn't tell me anything new.

Hello, If going into windowed mode doesn't work for you. try installing the beta version of steam. settings > interface > client beta participation.
