Audio Cut Out When Using Dereverb

I have recently started using Premiere Pro again to edit videos after a break of 9-12 months.

When I export videos using direct export or through ME, if I use Dereverb on my audio the exported files will consistently experience audio drop out when played back. 

I have experimented with other audio effect like Dehummer / Denoise and the audio drop does not happen with these. It is an isolated issue with Dereverb.

I've followed other posts advice and cleared my cache, audio input to none, reset workspace etc. It still happens consistently when using Dereverb.

I really need the benefits of Dereverb. 

Can anyone help with a fix for this please? I've searched the forums and Youtube.
