Sorbet type-checking freezes in my Rails 6 project with latest sorbet and tapioca versions

Question

We have a Rails 6 project and running into problems getting Sorbet typechecking to work. We have been following the adoption guide and getting stuck at Step 3 with no debug output or errors.

These are the versions we are running in our Rails app:

• rails (6.1.0)
• sorbet (0.5.10827)
• sorbet-static (0.5.10827)
• sorbet-runtime (0.5.10827)
• tapioca (0.11.6)

Observed output

1. using Tapioca to generate rbi files works and correctly generates a Sorbet config and rbi files for gems but hangs on Finding all unresolved constants and never completes.

pritikan@Pritikas-MBP rosie % bundle exec tapioca init
        skip  sorbet/config
        skip  sorbet/tapioca/config.yml
   identical  sorbet/tapioca/require.rb
       force  bin/tapioca

2. Typechecking hangs without any output

pritikan@Pritikas-MBP rosie % bundle exec srb tc -P
Indexing |=======================================================| ETA: 0h00m00s
Resolving |                                                      | ETA: 0h00m00s

Expected behavior

pritikan@Pritikas-MBP rosie % bundle exec srb tc

would return a list of type errors.

We have tried the above with 2 Rails projects and 1 Ruby project and find that the issues are with the Rails projects only.
