It was with the same songfile loaded made in 622 and imported in 623, and with RT exports. A sudden stop and cut off of all the RTs at the last bar (No 2bar endings or 4 bars for RTs selected in song settings). I reinstalled 622, exports were seemed normal again, and then installed 623 again. Now exports behaved normally .. Murphy at the wheel?

PS I'll mark the post as fixed ....Thnx

SIDELINER: rebuilding the song picker window gives this in 623:
