Nope. Since you have a modchip installed, your console should enter recovery mode on boot and launch the payload.bin file from the root of your SD card (usually it's the renamed Hekate's payload).
Don't you have an unmodded Switch Lite? Or did you recently acquired an unpatched V1? I'll assume that you now have an unpatched V1 as well.
It's definitely weird to see that you have multiple partitions on your SD card. Can you boot into OFW? If so, I'd suggest that you start from scratch by following either
NH Switch guide and
Rentry.org Switch guide in order to install CFW on your new Switch.
The only time I restored my emuMMC backup was when I switched to a new SD card by following
this guide (via NxNandManager).
Is the backup you're speaking of made from sysMMC or emuMMC? If it's emuMMC, I think that you can restore it, but I'm not sure what to do if it's the sysMMC one. If I had to start from scratch, I'd just create a fresh emuMMC.
As for the save files on the corrupted emuMMC, it depends on whether the USER partition is accessible or not. binkinator made a
decent guide on how to recover and restore those saves.
