System can not find the path specified

Hello all,
I am facing a problem with MIT APP Inventor Emulator. The app is not opening in the emulator. I the AI starter showing "System can not find the path specified" and "Problem in checking for the devices." I have posted the screenshot also. Please help me to overcome this problem.
Thank you


If your App is reading or writing an external file/data on the device, external device or the internet, that can't be emulated. The intended use of the emulator is to perform a quick test of your recent code, but it is much better to perform your tests via the Companion (much more stuff supported because it is on your Android Device) or ultimately testing a compiled APK.

But it should work. Right? How to rectify this problem ?
