Can’t switch to MacOS from Windows 10 with Bootcamp

I installed Windows 10 via

Bootcamp a few weeks ago. I have a MacBook Air 13" (macOS 12.7.6) and I encountered no problems, 1 could easily switch from Windows to Mac with the Boot Camp control panel. But yesterday I did a fresh install of Windows, and I think that removed all files related to Bootcamp, and so I can't use that to switch to macOS. I read that the other way to switch is by entering Startup Mode (shut down then turn on while holding Option), but this is what happens every time I try, and it has been like this ever since installing Bootcamp when attempting to enter Startup mode from Windows. It first has the loading symbol, then this appears. This is my Mac, I bought it from Apple, but I don’t know the firmware password. Is there a way to avoid this or any other way to switch back to macOS?
