Shotcut crashed suddenly for no reason

What is your operating system?
Windows 10 21H1 64 bit

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
21.05.18, 64 bit

Can you repeat the problem? If so, what are the steps?
I created my project today and after working just 30 minutes shotcut crashed, I also had task manager opened on my second monitor that I have connected to my same PC and when shotcut crashed it showed me it was using just 1% (i.e. 2.55GB) of my ram, 6% of CPU and 2% of GPU, I will write down my system specs at the last of this post. And I was just using shotcut at that time and no other apps were open at that time, so there was very low power usage but still shotcut crashed without any reason. I do not have any screenshots of what happened because the crash happened suddenly and I didn’t get time to do anything for it.

System specs:- Intel® Core™ i9-10900X X-series Processor (19.25M Cache, 3.70 GHz) with 256 GB Ram and a single GeForce GTX 1660 SUPER on msi creator X299 motherboard.

There must be some reason but we do not know what it is. Can you recreate the crash consistently? The best crash report will have some steps to reproduce the crash.

I did the same this time as before, and I noticed whenever I leave shotcut open without doing anything on it for 5 mins then shotcut crashes, And I was resting for 5 mins when it first crashed.

I think leaving it still for 5 mins or more makes shotcut crash.

I have left Shotcut open for days and not experience this problem. I think others would report it as well.

Is this the same computer that you report Shotcut does not work with >32GB memory? I wonder if there is something wrong with your RAM.

Have you ever run a memory diagnostics?

Yes that’s the same PC, but when I re-installed Windows it then started working. I only had this problem 3 days ago, otherwise on may 26th I left shotcut open for 6 hours and the ram usage at that time was 6gb but it doesn’t crash at that time. I also believe that there is just some problem with my RAM that just happened starting 3 days ago.

That is also my suspicion - which is why I recommend the memory test I linked above. If the test fails, remove sticks one-at-a-time until it passes the test. Then you will know which RAM stick is bad.

Right now I am using my smartphone to reply and I was only testing the RAM as you said but without opening the website I was just removing sticks manually and seeing them to figure out what happened to them and unfortunately😢, 1 stick was cracked and it was causing problems, sometimes it worked and sometimes it gets removed because of the crack So I think this also makes my PC restarts any time automatically.
