Shotcut switch off

Hello,
Very often shotcut switch off while handling.
What can I do to prevent switching off.
Best regard

Can I ask you which operating system to use and the features of your computer? For example, the characteristics of the processor, the ram installed and if you use a SSD or the previous and more recent generation with mechanical functioning as a hard disk?
Shotcut is a video editing program that can be classified as lightweight. However to work properly, he also requires the use of a not too obsolete computer.
In my PC not really ultra-modern, working with I7 processor, with only 6 megs of ram, and SSD hard drive, it works without problems.

Going to need a lot more detail.
