Sidekiq: uninitialized constant Sidekiq::Rails::Application

[AdamDemirel]

On a completely new rails app with installing sidekiq being the only action taken, I can't run any rails commands (not even rails c) without the the uninitialized constant error

Ruby version: 2.6.1
Sidekiq / Pro / Enterprise version(s): 5.2.5

Please include your initializer and any error message with the full backtrace.

Turns out naming the project sidekiq caused issues. (due to naming the config/application.rb module)
