Repro steps

I've updated an existing project from Angular 8 to Angular 9. I have switched Ivy off. Please find below my tsconfig.playground.json file.

{ "extends": "../tsconfig.json", "angularCompilerOptions": { "enableIvy": false }, "compilerOptions": { "outDir": "../out-tsc/app" }, "files": [ "src/main.ts", "src/main.playground-check-errors.ts", "src/main.playground.ts", "src/polyfills.ts" ], "include": [ "src/**/*.sandbox.ts", "src/**/*.d.ts" ], "exclude": [ "src/test.ts", "../src/test.ts" ] }

Observed Behavior

When I attempt to run playground, I'm seeing the error:

ERROR in ./src/main.playground.ts
Module not found: Error: Can't resolve './../../node_modules/angular-playground/dist/build/src/playground.module.d.ngfactory' in '...\demo\src'

Any other details that may be useful (optional)

Within the node_modules folder, I can see playground.module.ngfactory.d, not playground.module.d.ngfactory

Setting enableIvy to false and aot to false fixes this issue
