GSE TV crashing. Fixed - revert to older version

An app called GSE TV has started to crash on startup - it tries to open then the home screen pops up.
I’ve used it for a few weeks without any problems, there re isn’t an update for it and the Pico is up to date.
I just tried deleting and re-installing the app, but that hasn’t fixed it.
Any suggestions please, or is anyone else using it without problems?
