React Native error: No identifiers allowed directly after numeric literal

In react native I am getting this error : [SyntaxError: No identifiers allowed directly after numeric literal]

There is no stack shown. How do I even begin debugging this without any call stack?

Here is my App.tsx file. When I comment out getOrCreateAssociatedTokenAccount line the error goes away. When I uncomment getOrCreateAssociatedTokenAccount line the error comes back :-
