Recovery bootloop

[FrenchGithubUser]

Using poco f1 with crDroid based on android 11.
After installing multiboot.zip and recovery.img, when rebooting to recovery leaves me stuck on the multiboot recovery screen.
I flashed the uninstaller.zip but I then couldn't boot on my system anymore.
Fixed by flashing twrp from adb and then reflashing crDroid in twrp.
Everything's back to normal, no data loss, but for some reason multiboot recovery wasn't working (it was a build from 2019, idk if there is any earlier one)

PS : I did have the multiboot screen when trying to boot to system before flashing the uninstaller and the system could still boot
