If you can provide a reproducible example I'm happy to look at it

You could also try adding/removing the lines in the preload to see what triggers it:

(rf/clear-subscription-cache!)
(trace/init-db!)
(defonce _ (trace/init-tracing!))
(trace/inject-devtools!)

If I had to guess I'd say that the init-tracing! which monkey patches Reagent is the most likely candidate to cause an issue
