Transfer to LR

When I use Topaz as a plug in for Lightroom and I denoise a photo irt works very well, Then when I sharpent the photo it also works well. Photo looks great. But then when Topaaz transfers the photo back to lightroom if fails and I get a message that says “Topaz Photo AI either failed to start or did not finish successfully. Exit code 3221226505”
Any suggestion of what I might do ?
Thanks
