Invalid GPT signature - Switch

[kermitswaifu]

Hi everyone, so I got an issue I'm completely stumped on. I download the Plants VS Zombies Replanted for my switch. I downloaded it thru DBI, downloaded game and update. Downloaded great and installed. Tried loading it, crashed. Tried downloading thru tinfoil, crashed. So originally I was gong to ask what I could do there. But now, my switch crapped out on me and had to reboot. Well now I have a bigger issue.

I can't get past this screen which will either boot my switch to normal or go back to the hekate boot up screen. Which is great because I can still use my But once I try to load fuse.bin. I get this (See up). I have saved my files, than reformatted the SD card, and deleted and put in brand new Hekate/Atmosphere with Fuse.

So I have no more ideas and Youtube doesn't seem to answer what I'm looking for. Personally, I feel like it's because I downloaded PVZ and would like to delete it off the switch but as you can see. I can't get past this screen so I can't just go into data management, and I have no idea how to delete anything off an SD card, since it isn't obviously which file is for what game in the Nintendo file.

Thanks for reading, I hope I gave everything I can to help. I'm still pretty new to this.

How did you reformat the SD card? Because if you had an emuMMC on it, and formatted it on a computer, you may have inadvertently wiped the emuMMC partition from the card. Try using Hekate to format the card and to make a new emuMMC (basically, set up CFW from scratch following switch.hacks.guide for example)

That article looks helpful and may just happen to be right, but holy hell is that whole site 110% AI slop bullshit, I can't even.

Seem to a not well known guide, but the information seem good, I did suggested this in another thread before , it could be that his GPT (GUID Partition Table) is messed up or he has a bad SD card.

I reformatted it to Fat32 and backup everything. Put brand new CFW than put the files back (that I assume I need for my saves and things. I loaded it thru the launch with Atmosphere PKG3 emuMMC (was using payload fuse.bin if i didn't state before) and now it will load. But will crash not soon after. I've attached what shows.

I'd rather keep my game saves but at this point if I need to fully reset it. I can try that.
