Emulator can't find 'Linux version ' string in kernel image file
I was having this error and the cause was my Emulator running an old version. I went to SDK Manager and updated the Android Emulator
Tools > SDK Manager > SDK Tools > Android Emulator > Mark it checked to force update > Accept
After this, the emulator ran correctly
See @voghDev answer above,
