So the part that reads:
==> Using Ruby version 3.2.2 via /opt/render/project/src/.ruby-version
==> Docs on specifying a Ruby version: https://render.com/docs/ruby-version
*** Unknown ruby version 3.2.2 . Proceeding anyways ...
--2023-12-22 11:36:16-- https://cache.ruby-lang.org/pub/ruby/3.2/ruby-3.2.2%0D.tar.xz
Implies this is still the Windows file end issue, in your .ruby-version file.
*** Unknown ruby version 3.2.2 . Proceeding anyways ...
there’s unexpected whitespace after the version number.
--2023-12-22 11:36:16-- https://cache.ruby-lang.org/pub/ruby/3.2/ruby-3.2.2%0D.tar.xz
Which translates to an incorrect file being called from the ruby-lang.org (the %0D).
The %0D is again, part of the Windows carriage return, which would need to be corrected for Linux
