Comment:

 I re-tested in WordPress 6.1.1 and Twenty Twenty-Three, and confirmed that
 the template part is not available in the inserter in the block editor.


 Next, I opened the code editor mode in the block editor and copy pasted
 the following template part:

 {{{
 <!-- wp:template-part
 {"slug":"header","theme":"twentytwentythree","tagName":"header"} /-->
 }}}


 - The header shows correctly in the block editor
 - Saving the draft works without errors
 - The header shows correctly in the preview of the draft on the front
 - Refreshing the draft post works without errors
 - Publishing works without errors
 - The header shows correctly on the front after it has been published

 Editing:
 - Editing existing blocks inside the template part works without errors
 - Adding new blocks inside the template part works without errors

 ----

 Next, I switched to Twenty Twenty-One (classic theme).
 The previously saved post with the header that was copied from Twenty
 Twenty-Three displays correctly in the block editor.

 On the front, there is a message with the text: "Template part has been
 deleted or is unavailable: header"

 Editing the blocks inside the template part works without errors, and
 saving works without errors.
 After saving changes, the front still displays "Template part has been
 deleted or is unavailable: header"


 ----
 I am not sure if this behavior on theme switch is the expected behavior,
 but if it is a bug, it is a separate issue.

 I am not able to reproduce the reported issue and I suggest that we close
 this ticket.
