[URGENT] I've updated the Bolt version and lost every settings mainly Events, what should I do?

SPF

My Bolt stopps working, I've read the notice here https://doc.photonengine.com/bolt/current/getting-started/overview. So I decided to update my Bolt version.

In the package manager I clicked download and re-import. However I found all my previous settings including custom Events are all deleted. How can I find them back?

Thank you!
