After upgrading AS to Android Studio Flamingo | 2022.2.1 Patch 2 today, after opening a new project, the originally opened project was closed. very inconvenient. So I reset it, and the setting steps are recorded as follows:
1.Menu File->Settings
New windows means opening the project in a new window, and the original opened project will not be closed.
Current window means opening a new project in the same window and closing the originally opened project.
Ask means asking how to choose every time you open a project.
