Repro Code

classFoo{publicgetItself(): this{returnthis;}protectedthen(resolve:()=>void):void{resolve();}}

ESLint Config

module.exports={parser:"@typescript-eslint/parser",rules:{"@typescript-eslint/no-unsafe-return":"error",},};

tsconfig

{"compilerOptions": {"strictNullChecks":true  }}

Expected Result

No error, nor ESLint crash.

Actual Result

ESLint will crash because of an infinite recursion of thediscriminateAnyType function in type-utils/dist/predicates.js

Additional Info

When a class has a method returnthis andthis is also a Thenable,discriminateAnyType tries tochecker.getAwaitedType on it. I assume it results in the samethis type, which is then recursively checked infinitely.
