Hi
Other users have reported experiencing the same issue.
I suggest that you contact Twitter for assistance with issues concerning their app. Contact forms for filing a ticket are available here:
File A Ticket | Twitter Help Center
Whilst the options do not include an obviously relevant choice, you can select one that you feel is closest. Twitter can redirect the report as required, once received. For example:
Tweets & timelines | Twitter Help Center
Similar issues occurred following a prior watchOS update, which were resolved when Twitter updated their app.
