   Hi there!

   Do you have any plugins or extensions on the desktop app configured, or is this a fresh install?

   Thanks for reporting this! Based on the symptoms (white screen on Intel Mac) and your confirmation that it's a fresh install, this appears to be a duplicate of #7291.

   The root cause is that the desktop app uses JavaScript regex features (lookbehind assertions) that aren't supported in older WebKit versions. Intel Macs running certain macOS versions have an older Safari/WebKit that lacks support for this feature, which causes the app to fail during initialization.

   You can verify this by opening the WebView developer tools (if accessible) and checking for a JavaScript error like:

   SyntaxError: Invalid regular expression: invalid group specifier name
   

   I'm going to close this as a duplicate of #7291, which is tracking this same issue with more diagnostic details. Feel free to add any additional info there!

   Workaround: Unfortunately there isn't a simple workaround at the moment. The fix will require changes to how the app is bundled.
