I think whatever roots it had were minimal, so they'd pucker up quickly.
That said I struggle with Calatheas much more established.
They do fine for a few months and then crash and burn.
I've been told it's not high moisture they need but high humidity, which is what make me wonder about your outdoor one.
Good luck:)

Its pot size is way too big, and the soil mix looks very heavy. It also most likely did not get enough humidity.
It may not be done, I'd unpot it and see if you do indeed have any viable roots left. If you do repot it into a very tiny pot, like 2", in a better draining soil mix. If you can get it to re-sprout and put out new growth, only size up the pot extremely slowly, and give this plant as much humidity as you can

Without air circulation around the plants roots and proper soil moisture drainage, the roots suffocate.
