Issue with new version of activesupport

[julianhinz]

After fresh install of dropcaster I get this error:

Traceback (most recent call last):

If I manually uninstall activesupport-6.1.0 and install activesupport-6.0.0 all works fine. This issue here seems to be related: https://github.com/rails/rails/issues/40861

Solved this for me by adding explicit version for activesupport in my podcast project Gemfile

source 'https://rubygems.org'

gem 'activesupport', '6.0.0'
gem 'dropcaster'
