Have you run bundle on your app to see which gems are installed? It looks like maybe you’re using a version of bootsnap gem that isn’t playing well with the defaults for the Rails you have loaded.

please can you help with which version of bootsnap is compatible with rails 5.2

Generate a blank rails app with 5.2 and see what bundler installs. But I'm not sure how that's relevant to your previously described problem...
