If you are on Windows 10, go to the reliability monitor (just type reliability into the windows search box). Then look for a red cross at the time of the Photoshop message. Click on that cross and you should see a critical event for Photoshop.
Double Click on the Photoshop event and you will get a box showing details of what happened.
Post a snapshot here.
Note : If the details mention Lavasoft - then uninstall Web-Companion /Adaware and you should be fine
Since the dialog is Windows, the common problem is usually Lavasoft's Web Companion.
You look at Programs in your Control Panel, and if you see Web Companion, uninstall it and reboot your PC.
Let me know if that worked.
