Remembered that when i encountered exactly the same problem on one of my 1a's yesterday. It only occured when the lensboard was completly retracted (at infinity focus). This evening i took away the lensboard from the camera and discovered wear marks on the inside of the metalcolored shroud at the height of the lip of the release bar where it engages the release ring. Clearly that lip hits that shroud at infinity focus and IMO that's the source of all the trouble because that just gives too much friction for the release bar movement. btw A second Ikoflex 1a i have for spare parts shows wear marks on exactly that same spot. Guess this could have been a design or (more probably) production fault.
