Redmine

Good day everyone.
I'm a pretty weak newbie, but it so happened that I need to install Redmine 4.1.1 on MS SQL SERVER 2018, running on Win 10.
I' m using the following:

My problem is that every time I try to execute bundle exec rake generate_secret_token procedure, or bundle exec rake db: migrate
I get an error:

rake aborted!
NoMethodError: undefined method `alias_method_chain' for #<Class:ActiveRecord::Base>
Did you mean? alias_method
C:/REDMINEapp/blog/config/application.rb:7:in `<top (required)>'
C:/REDMINEapp/blog/Rakefile:4:in `require_relative'
C:/REDMINEapp/blog/Rakefile:4:in `<top (required)>'
(See full trace by running task with --trace)

As far as I understand, `alias_method_chain' shoud not be existed in Ruby versions above 3m but no matter how hard I tried to locate and get rid of this line, I couldn't find it. Honestly, I'm out of options.
Any help or advice would be greatly appreciated.
