5.4.20: EXT4-fs error (device mmcblk0p1): ext4_lookup:1700: inode #4950: comm rsync: casefold flag without casefold feature

5.3.9: without error

 

fsck cannot see errors on another system

 

For now, I came back to kernel 5.3.9

I found this file. It was unnecessary and I deleted it. However, I don't know how this file can be problematic for casefold.
