TWRP won't flash properly topic

Hi,

When flashing TWRP through fastboot I don't get an error in the command line so everything goes fine.
But when i try to boot i get the android error log.
But when i try booting to TWRP (fastboot boot TWRP.img) everything works fine?

Extra information:
Stock android 5.0.1 with sideloaded latest update

I would like a working recovery before starting to flash. I'm not new to flashing, but can't seem to find the issue here.
