如何解决在Mac os26 beat7 在使用幻灯片播放时，在没有第二块显示器的情况下，自动进入演讲者模式，且画面模糊

macOS 26 Beta7 的 PPT 或 Keynote 在“演讲者模式”中出现 渲染模糊（text blurry），即使未连接任何外接设备。

报告日志：

Subject: PowerPoint crashes in Presenter Mode on macOS 26 (Sequoia) Beta 7 — Objective-C nilValueForKey crash

macOS Version: macOS Sequoia 14.0 (26.0) Beta 7 (25A5346a)

PowerPoint Version: 16.100.1.25081721 (Office Beta Channel)

Error Log: SIGABRT in merp triggered by mso40ui -> [<PPNSSecureTextField> setNilValueForKey:@"maxLength"]

Issue:

• When trying to play slides (without any external display), PowerPoint auto-enters Presenter View.
• The screen becomes blurry and eventually crashes.
• The crash stack suggests an uncaught ObjC exception related to UI field logic: setting nil value to maxLength key.
• This crash does not occur on macOS 15.6.1.

Request:

• Please fix compatibility issues with macOS Sequoia's NSSecureTextField behavior and internal Presenter View logic.
• Or offer a flag to fully disable Presenter View in one-display systems.

Thanks.
