Unfortunately yes, resin has leaked into the inside of your printer. Luckily the resin is not conductive, so it can't cause a short circuit and damage the electronics, but it can sometimes prevent the machine from booting up until it is wiped away. But if your printer is still working, it should be ok. If the tray rotates with resistance now, resin may have gotten into the bearings. Try running a print with no tray and no build head, and see if it jams. If it does, then you'll need to send it in for repair (unless you feel comfortable taking the printer apart and replacing the bearing yourself). I also recommend unscrewing the grey front panel and wiping up any resin that you see inside the printer.
I'm sorry this happened! Check your messages for a follow-up.
