"The table does not exist" when trying to save an entry

I just installed the plugin on Craft 4. The installation looked successful:

*** installed simplemap successfully (time: 0.037s)

I added a field of the Map type, added it to an entry type, then tried to save an entry. I get this error:

In case it's helpful, I'm using Postgres. I have tried uninstalling and reinstalling the plugin, and removing and adding it again via composer.
