Hello, hoping someone else has experienced this and resolved the issue.

The Wireguard app has been running without issue for many months until today when I attempted to activate the tunnel and received the following error:

“Activation failure” Unable to retrieve tunnel information from the saved configuration.

If I try and edit the config the app crashes. Some details from the problem/crash report:
