Events Missing

My Events Calendar is missing! ALL events are gone and i get a 404 error message https://amycoello.com/events

The Events Calendar Plugin is missing.

I have tried to update it by following the instructions: https://www.ads-software.com/support/topic/no-events-found-3/

but I receive the following errors:

Unpacking the package…

Installing the plugin…

Destination folder already exists. /home/content/a2pewpnas01_data01/32/3881232/html/wp-content/plugins/the-events-calendar/

Plugin install failed.

How do I fix this without causing loss of all my previous events?
