What is your operating system?
Windows 11 x64

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.)
Older and new shotcut versions don’t want to work propperly with the sound and prewiew, it has worked before, this is strange it does not only not work with that… it crashes and gets very unstable when trying to edit, it has worked on my machine before.

I do not reproduce the problem, and I do not see anything wrong in the log. “propperly” is not very useful information.
