Wavelab Elements 9.5 hanging at end of render process

Hi,

I’ve used this install of Wavelab since it came out without previous issue.

Recently when I render a wav file it does the render as expected and then when decoding the audio file to show the new waveform, it pauses or hangs for 2 to 3 minutes at the 91% stage.

Photo attached.

Any ideas how to prevent this?

thanks
