ADB fails only for Flutter but not for Android in Android Studio...

It is very strange, but in Android Studio on my Mate Ubuntu 18.04 or just Ubuntu 18.04, AMD Ryzen processor when I create ‘Android Project’ ADB works well. But once I am creating ‘Flutter’ one, i have error Error initializing ADB: Android Debug Bridge not found. I tried start it on Android Studio 3.2, 3.2.1… I tried recipes from here - no way. I tried to downgrade ADB to 23.0.1 too as mentioned here.

adb in console (via Alt-F12) works well. But Device File Explorer shows Error initializing blah-blah and i can not debug and see files in emulators and device…

Here is log:

Same problem for me. (If this really is a ‘ghost fault’ then this ghost is going round. 😉 … Has anyone a solution to this? Thank you in advance! Take a glance here

Thank you so much ValeriusGC! You put me on the right track. 😃

4 all others - check: -> File -> Project Structure: -> Project (if it has a valid Project SDK) and under -> Modules -> Dependencies (a valid Module SDK)
