Android App Bundle (.aab) FileNotFoundException Error when trying to build

When ever I try to build my game I get a FileNotFoundException, I even tried an empty project but it still didn't work. Here is the full error message.

FileNotFoundException: Temp\gradleOut\launcher\build\outputs\bundle\release\launcher-release.aab does not exist

I am currently using 2020.3.8f1, I'll try to update in a bit

 

Now when I build to em.aab I get this

FileNotFoundException: Could not find file 'D:\UnityGames\Demo Android Game\Builds\em.aab'.

Thank you it turned out that I had 3 gradle templates from when i was trying to fix it before. Thank you!

 

Hi I have the same problem with you. How did you solve your problem? What do you mean by 3 gradle templates?

 

Dude you need to go in Player Settings->Player->Publishing settings->gradle templates
