I've never tested with the 3S Model, and you're the first person to report a problem with this device. Not many things usually cause this type of issue on the Meta Quest, so I'm not exactly sure what to suggest you try to see if it works, other than checking that its storage isn't full and that it's updated to the latest system version. If this problem is happening with the purchased version, you can either initiate a refund request yourself or ask me here, and I can contact the Itch.io team to have them issue your refund.
Viewing post in Crashes immediately on Quest 3S
I've collected some information about the crash via ADB and logcat below, perhaps some of it will help you debug.
It is practically a new headset so I have some suspicions there just hasn't been anyone else to try it on the 3S yet. It is updated and there is far more than enough free storage. If nothing comes of it, I'm not worried about the money - consider it a donation :)
After a little bit of investigating, I found this which is likely the culprit:

Also noticed this:
VrRuntimeCompatHelper: DevicesSupported : 4 devices, quest2|cambria|eureka|quest2|
This would indicate support for the Quest 2, Pro (Cambria), and 3 (Eureka).
This may be a version of OVRPlugin / Oculus XR plugin which doesnt support the 3S?
I'm extremely amateur when it comes to the technical side of Android so this may be totally incorrect, but maybe it gives you some leads at least
