Per the stack trace this is coming from the Mail app,.not Server itsellf. Though I don't see that app in your list of installed apps, it must be installed the code referencing that icon in your provided stack trace is in the app itself.

I found the mail app on my instance and disabled it, which allowed the dashboard to work. I'm guessing that means the app is broken or something.

Also something interesting:
`user@nextcloud:$ sudo nextcloud.occ app:install mail
[sudo: authenticate] Password:
mail already installed
user@nextcloud:$ sudo nextcloud.occ app:list | grep mail

• sharebymail: 1.23.0
  fdosumu@nextcloud:~$
  `

Anyways reinstalling the mail app fixed it
