Android: Mac screen recording broken (EACCES permission denied)

[jlfreund]

You must attach a Vysor Bug Report Link

To Reproduce Steps to reproduce the behavior:

1. Connect to Android device
2. Click video recording icon (icon starts spinning, to start recording)
3. Click video recording icon again (icon stops spinning, to stop recording)

Expected behavior File save dialog should appear to save the video recording

Screenshots No save dialog appears

Desktop (please complete the following information):

• Mac OS 14.5
• Vysor 5.0.7 Mac

Android (please complete the following information):

• Device: Retroid Pocket 3
• OS: Android 11
• Vysor Bug Report Link: When pressing the "Bug Report" button, I got a Vyzor error: "Bug report failed: Request failed with status code 500". However I think there is enough information here to keep this bug open

Additional context This reproduces 100% for me.

Things I've tried are: (A) Rebooting Macbook; Rebooting Android device; (B) Clear Vysor app data on device and verify all permissions work; (C) Verify screen capture works; (D) Tried monkeying with it, including another user's recommended workaround to start recording, then do a screen capture, cancel the screen save dialog, then stop recording.

Note, in the logs, I see the following error, even though Vysor app has File and Media permissions:
