Try executing npx ngcc manually.

The next time I have this issue, I'll definitely try this. I think you are recommending this because it will show more information, right? Does NGCC use a different loader than this one? registerNgModuleType (core.js:36228)

ngcc would compile your node_modules to be Ivy-compatible. In my case, I just add "postinstall": "ngcc" in package.json scripts to get rid of such errors.
