In most cases, updating, repairing, or resetting Acrobat fixes the issue quickly. Keeping both Windows 11 and Adobe Acrobat DC updated is the best way to avoid recurring problems.
If the issue continues even after reinstalling, the problem may be related to a specific PDF file or third-party plugin rather than the app itself.
