MD-0011-30031 Install Failed error | Flex Path - Smooth and Natural Navigation (UE 5.7) | Fab

Summary

There seems to be some kind of issue with FAB and it refuses to install the Flex Path on UE 5.7. It keeps showing the error MD-0011-30031. At the same time, there’s no problem installing the plugin on another engine version or installing other plugins from different vendors.
I even completely reinstalled the Epic Launcher and kept only UE5.7, but it doesn’t help. As soon as I try to install the Flex path, an error pops up immediately.
