Could be a problem with the vendor you flashed. If you still want to try Evolution X out, try flashing the newest firmware (not only the vendor) and try again. After flashing the newest firmware, follow the instructions on the first post. That should work.
I uses the official version of TWRP and it worked for me. (After a few attempts)
Thank you for the answer. Could you give me a short explanation how to do this? I tried to download and flash firmware from https://xiaomifirmwareupdater.com/archive/firmware/davinci/ with no success it kept booting to flashboot. Tried to flash before flashing image of EvolutionX and after flashing EvolutionX, then I tried to flash full MIUI image miui_DAVINCIGlobal_V22.214.171.124.QFJMIXM_aaab5b40c7_10.0 before the Evolution X with no luck.
I like Evolution X very much I use it on my other phone (Samsung Galaxy S8+) and it's working great there.
