Step-by-Step Fix

1

Check for App Updates

Developers often release "Day 1" patches for new OS versions.

2

Clear App Cache

Delete temporary files that might be incompatible with the new OS.

3

Run in Compatibility Mode

On Windows, right-click > Properties > Compatibility > Run for older version.

When to See a Technician

Major OS updates often change how apps access memory or files, causing older apps to break.
