Android studio need help.

In Android Studio, it appears to be loading in the background task section, but it never finishes. I left the PC on for 2 days, but there is no change. Does anyone know the solution to the problem. I couldn't find it on the internet.
Thanks

invalidate all caches and restart the app

Under File, select the Invalidate Caches / Restart option.

In the dialogue box that pops up, click the Invalidate and Restart button.

This is the most common fix for the issue.

If this doesn't work, we can investigate further starting with how many emulators you have running and/or how many devices you have plugged in.
