TWRP and root lost after OTA ROM upate

[FrankH]

Last night the system updater on my nuwa performed a ROM update to HyperOS 1.0.7.0.UMBEUXM and TWRP and root are no longer there.
Will I loose all my data if I flash TWRP via fastboot and then Magisk via TWRP?
Thanks for your advice.

If you don't make a mistake, you won't lose data
