Postdoc, country and comfort zone
I suggest that you pursue all options open to you at the current time and delay decisions until you are required to finalize them. In other words, apply for some positions in your home country and see what develops. If they then seem better than your current situation, then do that. But you can also pursue options in your current country with the same goal.
Just be honest with your supervisor, who seems supportive now and may be supportive of your need to be flexible.
Many of us had to make compromise decisions along the way due to such things as a bad job market. Now it is the pandemic. People generally will understand such things and that one can't proceed now as if things were normal.
