None of the existing solutions in the web worked (spent hours trying them all out, including a repair installation). In the end what worked was to delete all folders containing WindowsSubsystemForAndroid from C:\, including those in "C:\ProgramData\Microsoft\Windows\AppRepository" and "C:\ProgramData\Microsoft\Windows\WindowsApps\".
