Delete storage in 'Other Volumes in Container'? Hello,
can you guys help me

I did factory reset also I used OmniDiskSweeper did not help
‘Other Volumes in Container’ are other volumes independent from your currently booted operating system and its data volume.
In your case diskutil list shows disk1s5 and disk1s7 as additional Data volumes. Check the contents of these volumes in Finder (or with OmniDiskSweeper pointed at these volumes instead).
