[Can't export to JPEG, anymore!!!! CPU 100%, !!!]

Hi, 

Yes i can export and empty canvas with no problem. Even a a picture with one or 2 adjustments, but when i work with layers and i try to export doesnt react, just the CPU go to 100% for long time with no action.

I work with a folder on my desk where the photos are stored in .NEF (I have a Nikon d5300) and try to export them to the same folder in jpeg format. previously worked without problem. 

6016x 4016px, 24.16MP,  RGBA/ 16,.

 

 

In my previously processed photos, the affinity file size is around 250 to 290 MB, and once exported in JPEG, about 35MB.

Initially say that I am a beginner in photo editing. Affinity is my first edition software.
I acquired affinity about a year ago. I am happy with the program.
With the latest update, I can't export to jpeg. (Only after some adjustment to  the photography.)  When I try to export, The CPU reaches 100%, and affinity does not respond stays frozen with the export bar for minutes. It didn't happen to me before.
I did various tests, including uninstalling and installing.
Also look in my files for photos previously edited and exported to jpg. And select the Affinity file to test if I could export it, since I already did it months ago. But this time it doesn't work. It only happens to me since the last update.
