The KYS file in Adobe Premiere Pro is invalid

I am using macOS Tahoe 26.4.1 on a Macbook M4 Pro. I have been fighting with Adobe Premiere (both 25.6.5 and 26.2) because none of my hotkeys are working whatsoever. I’ve been having to manually click tools, the playback buttons, and timeline area to get anything to work. The spacebar seems to like to open a new instance of premiere every time I press it, which is tough because I usually use that key to stop/start playback.

When Premiere 26.2 is first opened, I get an error saying ‘The shortcut key file “Adobe Premiere Pro Defaults.kys” is invalid!’ and the app resumes loading. That same error does not pop up in 25.6.5, but the symptoms are the same.

Here’s what I’ve done so far:

1. I’ve held option while opening, and reset the prefs/cache/plugins numerous times
2. I’ve completely uninstalled all Adobe apps and Creative cloud, and used Adobe’s ‘Creative Cloud Uninstaller’. I then reinstalled CC + Premiere. No luck.
3. I tried manually copying the kys file form the app’s package contents, and placing it in the /documents/Adobe/Premiere Pro/26.0/[profile]/Mac
4. I’ve thoroughly gone through the Privacy & Security settings on my Mac, and gave Premiere Pro practically access to everything (including full disk acces, keyboard, etc)

I’m sure there are other obscure steps I’ve tried, but at this point I’m at a loss. We’re trying to push out several small videos a day, and having to use a mouse-only interface is infuriatingly slow.

Any insight would be appreciated, thanks so much.
