SD card port got super hot after replacing - is it safe to use?

The SD card port stopped working in my son's Switch so I replaced it with a third party one from Amazon, but when I put an SD card in (SanDisk 16GB), the Switch froze and wouldn't get past the startup screen. As one of his joy cons also wouldn't connect (a fun discovery I made when my only option was to reset the device) I decided to go back in and replace both slider rails on the console. This was a success and the Switch completed the initialisation process, but when I put the SD card in again there were some popping noises and when I tried to remove it, it was red hot and burnt my fingers - even though it had only been in there for a very short space of time. The Switch was on a very low battery and died at this point and wouldn't charge up, but it has started to charge again now, hence the edited post. I'm hoping it will be usable albeit without using the SD port if this is the problem, but is it likely to heat up again without an SD card in? Other than replacing components using YouTube videos, I'm no electronics expert, but does this sound fixable or do I need to get it looked at by someone who knows what they're doing?
