About this tag
Excel startup problems, such as slow opening, freezing, or crashing when launching Microsoft Excel, are often linked to software conflicts or recent updates. Common causes include antivirus software like Trend Micro's Worry-Free Business Security (WFBS) agent version 6.7.3981/14.3.1311, which has been reported to interfere with Excel after June 2025 updates.

Troubleshooting steps typically involve updating drivers, clearing Excel's startup folder, or running Microsoft's automated repair tools.
