Funny coincidence: I also had an "app" suspended yesterday and hit
the same issue (with clients in perl, python, and C).

Which is also not true anymore, AFAIK. My current understanding is:
- Twitter is over time suspending old "apps" (happened to me already
  earlier this year, and again yesterday).
- It's possible to create a "project" and move the old "app" there,
  thereby reactivating it -- but by the new rules:

* There are paid and unpaid plans with different features.
* Twitter API v1.1 is quite limited (for all plans).
Cf. https://developer.twitter.com/en/docs/twitter-api/getting-started/about-twitter-api


So the problem is not that Net::Twitter and Net::Twitter::Lite are
broken per se but that they don't support the Twitter API v2 which is
a pain as the API v1.1 is very limited by now (except for still
working old "apps") -- but I can confirm that uploading images with
Net::Twitter::Lite still works.
 
Apparently Twitter::API has some support for the Twitter API v2 [0]
which I still have to try.
