Crash on startup: Invalid URI: The format of the URI could not be determined.

Issue #6781 new
Daniel Waleniak created an issue

Hi there,

I am importing my ROMs into Launchbox and it repeatedly crashes on startup now attempting to download media. The program freezes and as soon as I close the below error window, Launchbox crashes. When I restart the program, the error occurs almost immediately again.

  • The version of LaunchBox you are using: 12.8
  • The version of Windows you are using: Windows 11 Pro 21H2, OS Build 22000.527
  • How often the issue occurs: each startup
  • Steps to reproduce the issue if you are able to reproduce it: download media for ROMs
  • The complete error that shows up in LaunchBox, if there is one (with all error text)

Invalid URI: The format of the URI could not be determined.

App: LaunchBox
Version: 12.8
Type: System.UriFormatException
Site: Void CreateThis(System.String, Boolean, System.UriKind)
Source: System.Private.Uri

    As a work around while we try to figure out what is causing the issue you can do the following.

    Close LaunchBox and BIg Box
    Navigate to \\LaunchBox\Data\
    Delete the ImageQueue.xml file
    Open LaunchBox

    After doing this you will need to re-queue your downloads but it should let you utilize the program again without that error appearing.
