Temporarily Disable Antivirus Real-Time Scanning
If you use McAfee Total Protection or a similar antivirus program, real-time scanning may conflict with Publisher. Temporarily disabling it can help identify the root cause.
Antivirus software aggressively monitors files as they open to prevent malware infections. Sometimes, this process creates a bottleneck or conflict with Microsoft Publisher, causing the application to lock up.
Launch McAfee Total Protection (or your specific antivirus software) from your system tray or Start menu, and navigate to the Settings menu.
Scroll down the settings menu to find the 'Real-time scan' or active protection option.
Turn off the Real-time scan feature. You will usually be prompted to select a duration; choose 15 minutes to allow enough time for testing.
Open Microsoft Publisher and attempt to load your files. If the files open normally, the antivirus is confirmed as the source of the conflict.
Add an Exception for Microsoft Publisher
To prevent future freezes without turning off your antivirus, add Publisher to your security software's exclusion list.

Reinstalling Publisher or the entire Microsoft 365 suite typically does not resolve the issue if the root cause is an external software conflict, such as your antivirus temporarily locking the files.
