After the job is completed, Python applications remain in memory that prevent the next job from starting. After 3-4 completed tasks, the next one hangs by 4%. The load on the video card is only an increase in the frequency of the memory. After restarting the computer, the tasks continue to run.

Until the situation repeats itself. Perhaps a separate failed task or a computer glitch. This was exactly the situation six months ago.
I look forward to repeating, each task is completed in about two days.
