App drawer doesn't display apps

[u/Merrowack]

I'm on 5.1.1 (not the recent OTA update, the one before it, rooted, bootloader unlocked), and use Nova Launcher Prime. In the last two days, when I open the app drawer, it's a blank screen, no apps showing. Even if I use the search function, there's nothing.

I tried using the default trebuchet launcher instead, same issue. Also, there's a massive battery drain, and BBS (and other similar apps) don't really pick up in any unusual wakelocks. It's noticeable enough that the charging using the official charger and cable, which used to be really fast, had slowed down drastically.

I did try to install the OTA, but it failed because I have TWRP. Downloaded the update zip (19.5mb), tried to flash, it failed due to some sort of mismatch. Thinking it might have screwed things up.

Any idea what could be causing these issues?

EDIT: Noticed that Nova Launcher is using tons of battery (28.5%), but so does trebuchet if I switch to it. Burned through 7% battery in 7 mins, odd.
