Some news, but fail
I have put a 128Go Sandisk Extreme SD Card (from my camera) to do all from scratch, with the original Shetix HATS 1.71-5 pack, create new emuMMC extracted from the genuine 16.10 firmware inside SysMMC of my Switch v2 : same problem "Oops! Something went wrong." after the little orange circle at the bottom left.
I have also tried to upgrade to 18.10 with Daybreak: same problem.
Some questions (to help me) to those who Crunchyroll works well on their switch:
1) Which emuMMC/AMS firmware version do you use ?
2) Have you linked the account with linkalho or another .nro ?
3) Have you hide your NSW serial in the "exosphere.ini" with "blank_prodinfo_sysmmc=1" and "blank_prodinfo_emummc=1" ?
4) Do you put the patch file inside "atmosphere\exefs_patches\CrunchPatch\" folder
or as the 1.5.0 version here "atmosphere\exefs_patches\cromchroll\" ?
(file "3FFE1F86EA117F96E5104AB66382DEBC00000000000000000000000000000000.ips", 19 bytes size)
Also, could you share the files inside the "atmosphere\hosts\" folder (or copy the content as it is text value) ?
Thanks for helping me
Edit 2024/11/04: I have tried with another empty SD card from scratch.
Not a single way to make this work

And if I try without the .ips file from scratch also: I have exactlly the same problem.
=>So I'm pretty sure that there is a problem with the .IPS file, or maybe some missmatch with my Crunchyroll 1.9.0 installation.
Also, I have reversed the .isp to pchtxt file, and I think I have a problem with the line
@nsobid-3FFE1F86EA117F96E5104AB66382DEBC00000000000000000000000000000000
@disabled 009E2498 1F140071
which may not be the good offset one for me.
But I'm stuck as I have some lack of knowledge for that
