this recovery fix the issue at least for me (app automatically disappear after a reboot)Guys I'm pulling r27 and twrp v12.
I encountered a couple data corruption situations, specially a rather troublesome one (for some people that want to use a lower revision of f2fs, let's say in stock kernel).
I will be keeping the f2fs present on OOS until further notice.
I recommend you backup your working system and put it on PC, USB or similar.
seems it include some f2fs commits
take a look
