That error results from a failed service call before the application really does anything, so it might be firmware-related. I have not personally tested on the latest firmware, but libnx has been updated to 4.10.0 as of
this release. If anyone else could confirm whether they encounter the same error on the latest firmware, that would help.
In the meantime, could you try deleting the NRO, replacing it with the
latest release, shutting down your Switch (completely, not Sleep Mode), turning it back on, then launching the application immediately via title override? If that fails, a few questions:
- Is your Switch modchipped? (Assuming so since it is a Switch Lite.)
- Are you launching via HBL? If so, is it up-to-date?
- To verify, is there at least one registered user with savedata for one of the supported games?
