I restarted emacs with org 9.6.3 and reloaded it uncompiled and
did M-x toggle-debug-on-error to turn on backtrace on error.
I have also attached a copy of what my org-capture-templates
variable looks like.
Comparing these backtraces to my org-capture-templates,
you can see that only some of them fail (the ones corresponding to
'd', 'e', 'r', 'Rr', 'Rg', and 'Cc')
They all worked up until Org 9.6. They still work under Org 9.5.5, so
I don't know what changed.
These backtraces were produced when I hit C-g to abort a
capture template that got stuck on
'clipboard pasted as level 2 subtree',
Let me know what you think.
Here are some of the backtraces generated:
