Found a new fix that works with LiveContainer too!
Download this fix and install this fix in LiveContainer.
Tap the circle and select Enable Login
After successfully logging in, delete the app from LiveContainer but KEEP THE DATA FOLDER (make sure to remember the container's ID)
Install the latest version of NeoFreeBird from Releases
Before starting it, hold the app and enter Settings and select an unused data folder (the container ID you used for the fix)
Start the app and it should be logged in already.
