Adobe Acrobat Reader Always Reverts to Classic Mode (User Profile Specific)

Hi everyone,

I'm encountering an issue where Adobe Acrobat Reader continuously opens in the Classic/Traditional experience, even after multiple attempts to switch to the new experience.

Troubleshooting completed

• Repaired the installation via Help > Repair Installation
• Confirmed Acrobat is fully up to date
• Uninstalled and reinstalled through Adobe Creative Cloud
• Switched to the new Acrobat experience, but it reverted to Classic after restarting the application
• Reset Acrobat preferences by renaming the Preferences folder
• Used a different installer (https://get.adobe.com/reader/), signed in, and enabled premium features
• Fully uninstalled Acrobat and removed all Acrobat-related registry entries
• Reinstalled Acrobat from scratch

Findings

I tested with a different Windows user profile on the same computer, and Acrobat opens in the new experience without any issues.

This suggests the problem is tied to the affected user's Windows profile rather than the Acrobat installation itself.

Question

Before I proceed with creating a new Windows profile or performing a profile reset, are there any additional Acrobat user-specific settings, cache locations, registry keys, or profile-related fixes that I should try?

Any suggestions would be greatly appreciated.
