Why does restoring my backup.ab get stuck at restoring efs2?

I made a backup.ab straight to my PC from twrp since I didn't have enough storage on my phone, not thinking much of it. Now when I try to restore it, everything goes fine except for the last part where twrp tries to restore efs2 and gets stuck on it. I can't install other ROMs after this either and my phone is practically a brick right now. What can I do? Any kind of help is appreciated.

.AB - files are TAR-archives. Hence you can try to extract them by means of Android's TAR applet. TAR is also available in Windows OS as command line tool.
