MacBook Air drive not showing

So you didn't erase/reset. Boot into the Recovery volume (boot with the Command + R keys held down  - Intel Macs) or  (How to Boot an M1 Mac into Recovery Mode), select Disk Utility and repair all available volumes. Then reboot normally and see if you can.

If that doesn't help, boot again into Recovery volume and select Install System. It will not affect the user data.
