Premiere Pro reports “Adobe Premiere Pro Defaults.kys” is invalid on every clean installation and Beta crashes when opening Keyboard Shortcuts

System information

* Premiere Pro 26.3 (latest)
* Premiere Pro 26.2 (same issue)
* Premiere Pro Beta (same issue + crash)
* Creative Cloud Desktop (latest)
* macOS Tahoe 26.5.2 (latest)
* MacBook Pro 16” (Nov 2024)
* Apple M4 Max
* 128 GB RAM

Problem

Premiere Pro reports:

“The shortcut key file ‘Adobe Premiere Pro Defaults.kys’ is invalid!”

This happens on every launch, even after a completely clean installation.

Additionally, Premiere Pro Beta crashes immediately when I open Keyboard Shortcuts.

What I already tried

* Completely uninstalled Premiere Pro.
* Reinstalled multiple versions (26.2, 26.3 and Beta).
* Deleted Premiere preferences.
* Deleted keyboard shortcuts.
* Deleted workspaces/layouts.
* Used Creative Cloud Cleaner Tool.
* Installed from scratch again.
* Restored default preferences.
* Tested with completely new preference folders.

Nothing changes.

The application still reports that the default Adobe keyboard shortcut file is invalid, even though it is the original file installed by Premiere.

Expected behavior

Premiere should launch using its default keyboard shortcuts without reporting that its own default .kys file is invalid.

Premiere Beta should not crash when opening Keyboard Shortcuts.

I have attached screenshots of:

* the error message,
* the Beta error message.
