Flask werkzeug detecting change and reloading without any edit of source files

TLDR

Update your Werkzeug version to the latest available (at the time of writing 3.1.3 solve the issue).

Long version

When running Flask locally through app.run(debug=True), I had a very strange issue of random reload of the local dev server when doing any request raising ConnectionError since the connection was aborted while restarting the server. The reload kept happening at every request because of source file change even through my editor was closed.

Investigating the issue briefly, it seems that it was caused by a bug in Werkzeug, updating it resolved the issue.
