The ucrtbase.dll mentioned in the error messageis a Microsoft C++ component, on my laptop.
Check the following, in the order given, testing the export after each step:
If there is a transition or effect on a clip at the point on the timeline where the crash occurs, remove it then try exporting again.
Run a system file check - see this tutorial and do steps 3 - 11. the tutorial also applies to Windows 11
If the issue is still not resolved, check the version number of the ucrtbase.dll file which is installed in the Windows/System32 folder, then download and install both the appropriate x86 and x64 versions of the Visual Studio C++ redistributable from here - select the version matching the first 2 digits of the version number of the file, eg if the file version begins with 10. then this is the 2010 version
Your problem may be due to outdated drivers? Upon checking the uploaded specification, I see that your Intel(R) Arc(TM) A770 Graphics driver is no longer up to date.
Your version is 31.0. 101.545, while the latest version is 32.0. 101.6130_101.6048. You could have this checked automatically by: Download Intel Drivers and Software
HTH Rob
PS. If you find it annoying or do not dare to update your computer to the latest drivers, I advise you to have this done by a reputable computer store
I'm a little confused by all this. I may have missed something so I'm afraid I'm going to ask what is possibly a very silly question - why don't you use the Arc A770 for Importing, Processing and Exporting?
My guess would be that your CPU got maxed out as you appear to use it for both processing and exporting; changing your setting to have the Arc A770 doing the processing took a lot of the work off the CPU and the encoding completed without crashing.
Set all the settings to the Intel Arc A770 and your encoding should fly.
As I said, I may have missed something, if I have then apologies.
So I can/have assumed that you still have an out of date intel intel arc a770 in your PC. My advice, is therefore justified to refer you back to the PC shop.
I am very pleased to hear from you that after following all our sincere advices your crash problem has been solved. My advice is to check every now and then if your drivers are still up-to-date. I do this once a month myself.
You wrote earlier: "I updated the drivers for my video card and everything is fine" and now you write: "My computer kept trying to update these drivers via the card checker program".
Again, I would recommend contacting the computer store where you bought your system. They should be able to tell you how to keep the Intel drivers up-to-date.
