A. If exporting to 1080p fails, first check your device's storage space. Ensure you have enough space for the export. If space is limited, free up some storage by deleting unnecessary files or apps.

B. If storage is sufficient, try exporting the video in a lower resolution first (like 720p) to see if that works. If it does, you may need to adjust the settings or check for any app updates that could resolve the 1080p export issue.
