I moved back all 4 tabs and keyboard lifted from the right but not from the left. After multiple attempts to no avail I tried pressing the loose right back in hoping it would realign and lift at once but it snapped into position and wouldn’t move. I even removed all 4 tabs from their place to no avail. Somehow the keyboard is snapped in place without the tabs playing any part. I looked up a video on what to do and stumbled on this. Still no clue what I can do to free the keyboard.
