The issue you're encountering is likely due to the way the fiber interruption is being handled. I...

      const picturesJob = yield* Effect
          .tryPromise(() => {
            if (client.pupPage) {
              return client
                .pupPage
                ?.screenshot({ path: `screenshot_${Date.now()}.png` })
                .then(constVoid);
            }
            console.log('No pup page');
            return Promise.resolve();
          })
          .pipe(
            Effect.schedule(Schedule.spaced('1 second')),
            Effect.forkScoped,
          );
 
       client.on('ready', () =>
          Effect
            .gen(function*() {
              yield* Effect.log('Client is ready! open the latch');
              yield* isLoggedIn.open;
              yield* Fiber.interrupt(picturesJob).pipe(Effect.fork);
            })
            .pipe(Effect.runPromise));
