Research direction
Examine bili's rollup configuration file (likely in the bili package) to see how external modules are handled. Look at the error trace which points to rollup's internal module loading. Check if the node resolve plugin is properly configured to handle Node.js built in modules like 'util'. Also inspect the watch mode setup in bili to see if there's a difference in module resolution compared to a single build.
