Shotcut does not work on every computer. Information was provided in the FAQ and Display Method docs about compatibility.
It generally works stable for the developers. If there is a specific thing that causes a crash, it needs to be be specified. Otherwise, general instability implies a compatibility problem with regards to technology used. In that case, you can try to debug the general issue and submit a fix or simply use something else that works for you.
From now on, if you submit a crash report without specific information and steps, I will simply hide it. I am closing this now. Start a new thread with specific details and steps if you have them.
