I don't know much, but seems like eMMC is damaged or full on corrupted. My first step would be to open it up and reseat the eMMC inside to see if that fixes anything. A loose/missing eMMC will cause the device to auto boot to RCM similar to autoRCM, and the error messages indicate it can't communicate to the eMMC.

Please can you show me
I'm new in the switch :(
You have to take the back cover off the switch and then remove the metal shield that is under that. After that you should have direct access to the eMMC which is a separate daughter board. My guess is if the eMMC isn't damaged or outright missing, pulling it out and putting it back in to reseat it will fix the issue.
Unfortunately I'm at work so I can't exactly show you, but I may be able to take some photos showing what to do once I get home if someone else doesn't show you by the time I get home. There's likely already a video out there already, and I believe ifixit has a teardown guide that you can look at and do the beginning part up till you get to the eMMC.
