Could not locate the OS X boot volume

Hi,

I installed Windows 10 onto my MacBook Air High Sierra using bootcamp. The windows is working great but I cannot get back to macos. I tried the two different methods: restarting while holding option (it just restarts windows) and clicking on bootcamp in the bar but It says "could not locate the OS x boot volume". I have read another response Could not locate the OS X boot volume - B… - Apple Community but none of these suggestions helped. Any advice or guidance would be greatly appreciated!

MacBook Air 13″, macOS 10.14

Run a SMC and NVRAM Reset and us ether Alt/Option method and test. What is the year/model of your MBA (do not post the serial number)?
