Describe the issue

The send button appears to disappear fairly regularly in the latest version of Microsoft edge 131.0.2903.112. I see it twitching and when I start to type an email it then disappears. The only way to send the message is to save the message, open it as a draft and then send it that way. This seems to happen on all messages.
