}

Steps to reproduce the bug

Add the following code when using typescript 5.0(Not having an issue before)

export class TypeEmitter<T, TOptions extends object = Record<string, never>> {}

export function createAssetEmitter<T, TOptions extends object>(
  TypeEmitterClass: typeof TypeEmitter<T, TOptions>
): void {}

• TypeScript version: 5.0 (working before)
• Node.js version: v18.8.0
• OS: OSX

This appears to be because TS before 5.0 didn't preserve the query type when dealing with types (as you can see by pasting this into https://ts-ast-viewer.com/), so I never noticed before now that TS doesn't always give a symbol. I've asked in the compiler API channel of the TS discord if there's a better way of doing this.
