Photolab 6 crashing MacBook Pro

Had an update to PL 6 last week and now denoising a batch of photos takes hours, and when nearly complete I get a message ‘Your computer has run out of application memory’, followed by a crash that loses all the work. I have deleted several applications but I think it’s PL that is the culprit. Anyone had similar problems? I will have to ditch DXO if this goes on because it’s unusable.
