Title:
Strange Characters (e.g., "HNY6") Appear When Pressing Spacebar with Caps Lock On (macOS Sequoia 15.5)

Description:
I’m experiencing a bug in Adobe InDesign (latest version) running on macOS Sequoia 15.5 using a MacBook Pro. When Caps Lock is on and I press the spacebar while typing, instead of inserting a space, InDesign types a string of random characters like “HNY6.”

This issue happens consistently and seems isolated to InDesign. Other apps (like Notes or Pages) do not show this behavior. I’ve confirmed the problem still occurs after disabling third-party keyboard tools and checking input sources. It only happens when Caps Lock is engaged and I press spacebar.

Please investigate and resolve this compatibility issue. It impacts workflow significantly when working with all-caps text.
