Rename the {path-of-android-studio}/lib/gson-2.7.jar file to gson-2.7.jar.disabled.

Restart Studio.

Import backup settings of Android Studio 

..that we saved beforehand to some safe place such as Google Drive

Restore default settings

Android Studio menu ->

File ->

Manage IDE Settings ->

Restore default

Uninstall and install the studio again 

(costly solution). 

Find out where and how studio was installed:

- Go to the parent directory of Linux in terminal: cd ~

- Find the android studio directory: find . -type d -name android-studio

If it is in snap folder, commands for uninstalling and installing are simple:

- sudo snap remove android-studio

- sudo snap install android-studio --classic

Use Android command line SDK and Vim instead of Android Studio for developing

Android Studio is based on Intellij which is kind of crap.
