Don't just "nvm fixed". Explain how so others can fix if it happens to them.
I got the same problem a while ago, i fixed it by going to SD:/ReiNX/Titles and deleting the Album folder.
At this point the Switch boots but the homebrew menu does not open.
Just got to ReiNX site and redownload the Album folder, put it in your SD card where the previous was and you'll be fine.
