Mi Note 10 (Pro) After formating data in any custom recovery only fastboot is possible

I'm now on miui_TUCANAEEAGlobal_V11.0.17 and want and could install twrp-3.3.1-3-tucana-mauronofrio or recovery-TWRP-3.3.1-1118-XIAOMI_CC9PRO-CN-wzsx150 using fastboot and can restart into recovery. When I execute the command "Format Data" I end in the fastboot-mode and a reinstallation of any - even stock- recovery fails and the device remains in fastboot.
What can I do?
