Lightroom cc classic hangs/stops exporting files

[Achtenburg]

I do real estate photography, I edit some 200 photos and 200 short videos (4-5 seconds) per day by lightroom.
After I finish editing, I put all to export and I face the following 2 problems:

1. second and/or third file of the folder never exports
2. stops exporting and hangs in the middle of the process

Turned GPU off, no help.

Did anyone face this problem?

When did the problem first occur? Did you update yesterday 4.24.18?
