Fire UX team in time, 2025 edition.
Using Android Studio (2024.2.2) after a while.
So I have "Run" button at the top and another one with just different color in sidebar. Both tooltip "Run", only differ in shortcut.
Difference?
First one runs the project. Second one opens the Run pane at the bottom, which happens to have yet another button to run the project.
You had good old school UI two years ago!
