PlayCover GitHub Issue

Copy/paste into the PlayCover GitHub issue form. This version avoids code blocks except for actual logs.

App Store link

https://apps.apple.com/cn/app/%E4%BA%91-%E5%8E%9F%E7%A5%9E-%E7%A9%BA%E6%9C%88%E4%B9%8B%E6%AD%8C/id1569029742

Current issues

Game fails to install
Game fails to open
Game crashes randomly during gameplay
Game does not work with keymapping
Game experiences graphical issues or broken UI
Game fails to connect to servers or complete download

More details

Important clarification: The app itself launches normally and I can update resources and log in.

The failure happens only when starting the cloud game session (pressing Start Game / 开始游戏). It immediately shows an error popup:

English (HoYoverse/global release): “Game Failed to Launch” → “Parameter error”
Chinese (China mainland release): “游戏启动失败” → “参数错误”

Regression / timeline (approx.)

Last known good: Genshin Impact Version 5.5 (released 2025-03-26). I played around Mar–Apr 2025 and it worked normally in PlayCover.
First noticed broken: since around Genshin Impact Version 5.6 (released 2025-05-07). I started noticing the issue around May 2025 and it has persisted since.
I did not intentionally change any special settings. The main changes over time were game/app updates.
PlayCover stable 3.1.0 (1369) shows the issue. I also tested a nightly/beta build (build number not recorded) and the issue still happens.

Repro steps

Launch Cloud Genshin (云·原神) in PlayCover.
Click Start Game / 开始游戏.
The error popup appears immediately ("Parameter error" / “参数错误”).

Expected result
After clicking Start Game, the window starts normally.

Actual result
An error dialog appears immediately when I click start game(“Parameter error”), and the game session does not start.

I have a feeling this is another Keychain related thing but not too sure, will check.
