Did you read the line just above “unable to compile”? It actually explains you the error that it already got the Xsolla plugin defined. You probably have that plugin installed both in the Engine and in the Project. Delete one of them. ---

For me, the problem was that the project name has an unacceptable “-” special character in the name. Even though previous versions of the engine allowed it, starting with 4.26+ when creating a brand new project with that character it will through an immediate tooltip warning and disallow it’s use: close UE\>go to the project folder and rename the project folder name as well as the .uproject\>delete the intermediate folder\>relaunch UE\>repackage for Android (File\>Package\>Android) Having a whitespace (blank space " ") in the project name may also be disallowed, and this includes the project folder (not just the .uproject). It seems overall, Android has more strict requirements for packaging but doesn’t provide the proper debug messages to determine the issue. ---

It happened with me too: „unable to compile source file“. I checked the log and found something is wrong with XSolla. So I found it in UE/Plugins/Marketplace and delete all 3 XSolla plugins I had ---
