Fatal error: Uncaught TypeError when importing blocks

Hi,

When importing blocks (any block) through Starter templates on a page I get the error below. The importing is stuck in “Importing…” and when I open again I get the error and am unable to access the page except if I revert to an earlier revision.

I’m using PHP 8.0 and WordPress 5.7, Starter templates version 2.6.2. No change when deactivating all other plugins, so doesn’t seem to be a conflict. Please advice.
