Here is my flutter doctor -v or found issues in 3 categories. I google those to find solutions but nothing helps. I see there are errors saying faild to start adb when I open my emulator and another notification says daemon is terminated. After a few months, I come back with a new project and now I can open the emulator but it is not connected with my project (with my old projects too).

A few months ago, I still can open my old projects and run them on an emulator. I have a problem with the emulator that I cannot run my app on it.
