My phone stuck on OS boot animation but I can use adb to connect to it, how to fix it without losing data?

I have a Samsung s10e g9700 flashed with Corvus OS gsi (seems based on phh's gsi), which worked basically fine for almost a month. But when I flashed a modified system.img based on Corvus OS gsi, the phone stuck on OS boot animation (endless loop). Then I flashed back to the origin Corvus OS gsi , but the phone still stuck on OS boot animation. I'm sure that I have only flashed system partition and the origin Corvus OS gsi can work. I don't know why my phone cannot boot. But I have found that adb can be used when my phone stuck on OS boot animation, so I have got some adb logcat: logcat1 logcat2 logcat3 I have not backup my userdata (there is no twrp for my device), and the data is FBE locked , so is there any ways to fix it without losing my data?
