Crash opening my project

What is your operating system?
Windows 10

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

Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
I’ve been working on some smaller projects in the past, but this time I decided to use some more effects. I’ve never used Proxy and the program worked quite well, but now with this project I couldn’t get the preview to run smoothly. I saved it, closed the app and started it the next day, loaded up the project only to see that I can’t do anything - preview won’t even start, trying to create proxies (or do anything else) crashes the program. I have also updated the program to the newest release. I have no idea what to do with this, because everything I’ve tried so far resulted in a crash. If there’s any info I should give to solve the problem, I’ll give it as soon as I can.

Please give information on your computer’s CPU and RAM.

What is the video resolution on this project you are having trouble with and what is the duration?

Have you tried something very simple like start Shotcut and choose File > Open Other > Noise?
Did you reboot and try again?

CPU - IntelCore i5-7400
Ram - 24GB
The project resolution is 1080p (60FPS), so far it’s somewhere around 2.5 minutes.

Opening that specific project seems to be an issue, opening Noise or starting a new project from new clips works very smoothly.

Upload your project file, and I will use my own media. But there is a very strong chance I will not be able to reproduce it.

fnks17.mlt (53.5 KB)
is this file what you wanted me to upload or something else?

Yes, and I checked it for an obvious problem I did not find. It loaded OK without any media. I substituted my own media the first time, and the videos I chose were not long enough. So, I repeated it with some long videos, and it is working. I can play through it. I am not in proxy mode. So, I am not sure what the problem is on your computer with your media.

Today I tried to open the project again and to my surprise, I didn’t crash. The preview is laggy though, so I’m taking the opportunity to export the project I’ve done so far to use it as a clip later. Thank you for the time spent helping me, in case I have any further questions, I will ask them here.
