Neural FIlters (Photo Restore) frequently crashing

The neural filter 'Photo restore' is nealy useless: crashes 90% of the time with an error message "We have temporarily disabled this filter because of a problem'. What problem? Where can I look it up?

Because this filter is painfully slow, I allow it to 'work' and wait patiently (playing with my phone so I don't use the computer and ause further delay or a crash). So I don't notice when exactly the above error pops up, but

- it is guaranteed to happen when you change defaults and try to adjust any setting touching the sliders. If you leave it on Default and keep your fingers crossed, it may sometimes work.

- even with Default settings, it sometimes freezes/crashes straight upon launch.

This is only and specifically with the Photo Restore filter; the other neural filters (I've tried a couple) appear to work normally. Overall (ohtside 'Neural') the PS Beta is, well... more or less the PS we know and works.

Looking forward to a fix -

Thanks,
