How do I automatically send crash reports?

Hello Luiz Arantes Sa! What kind of crashes do you mean? Does Rider stop responding or crashes completely? To troubleshoot the issue the best choice would be to create a Support Request or Youtrack issue and attach log folder there (Help -> Show logs in Explorer). Especially, thread dumps are helpful.

Sometimes when I'm using Rider, there is a red exclamation mark at the bottom hand-right corner. How can I automatically submit these crashes so that I don't have to click on the red exclamation mark and hit send?

Luiz Arantes Sa, These reports are most useful with steps to reproduce or at least any description. That is why there is no option to send them automatically.
