Mi 12T Pro - XiaoMi Wallet is not working

[Eric_14]

Mi wallet is not working on MIUI_Diting_v14.0.23.4.17DEV Beta. I would like to copy my door card via mi wallet but it's not working(all functions is not working, not only mi transit and car key, even selecting key card it also not working) and it shows that wrong device information. I've checked the 'smart card' app via mi app store(which call getApp in global), it shows that "This application is not adapted to this model". Is it any solution to fix it?
