I think the best thing to do for you is post the exact steps you take with the details of the twrp version and the rom version. It's easier for the experts to tell you what to do next.
For example, I used: twrp-3.7.0_12-v7.0_A12-star-skkk.img and xiaomi.eu_multi_MI11Pro_MI11Ultra_V14.0.6.0.TKACNXM_v14-13.zip. My previous installation was MIUI 13 with Android 12, so I chose the A12 twrp version.
- Copied the rom to the internal storage of the phone
- Started fastboot, device recognized, booted in to twrp through fastboot boot twrp.img (renamed the twrp file to this)
- Phone booted into twrp
- chose install, browsed to zip file, use slider to start
- after errors, chose system then reboot
I can imagine you should select format in twrp after installing different versions. Make it easy for anyone to help you by describing everything you do so they don't have to ask for details for every step.
Keep the faith!
