Comment (by TJNowell):

 Investigating further, the templates in question had differing block
 markup:

 I found this on the templates that triggered the fatal error:
 {{{
 <!-- wp:template-part {"slug":"footer","tagName":"footer"} /-->
 }}}

 This however did not trigger the error:
 {{{
 <!-- wp:template-part {"slug":"footer","theme":"my-theme"} /-->
 }}}

 I do not know how this difference occurred
