The Windows app says it crashed or exited unexpectedly last time. What should I do?

After 5UF crashes or exits unexpectedly, the new Windows app shows a prompt the next time it starts, so you can report the problem. A normal shutdown or upgrade doesn't trigger it.

Buttons:
• View details: see when it was detected and the related logs.
• Export: save the crash record and logs as a zip file (5uf-crash.zip) to a location you choose.
• Dismiss: close the prompt for this occurrence.

Recommendation: if it happens often, click Export, then submit a ticket with the zip attached and say roughly what you were doing. URLs and similar private details are removed from the exported logs, which are used only for troubleshooting.

The Windows app also restores the system proxy automatically after an unexpected exit, so browsers no longer lose internet access. If pages still won't open, reopen 5UF or restart the computer.
