  • Your screenshot identifies an installer extraction failure: error 7, 0x80040902, with the message that the archive could not be uncompressed. That does not establish that your browsing profile is damaged. Since reopening Canary has not helped, restart Windows and check that the system drive has adequate free space. Download a fresh Canary installer from Microsoft's official Edge Insider download page, close Canary, and retry installation. Preserve your favourites and other important browser data before any uninstall; deleting the profile should not be the first response to this installer error. If the fresh installer fails identically, record its exact error and check security-product logs for a blocked or quarantined file without disabling protection globally. Canary is a frequently updated preview channel, so report the problem with version 155.0.4268.0 and the error details. Use the released Edge channel for essential browsing while the Canary installation issue is investigated.
