Player hangs after inserting clip

What is your operating system?
Windows 11 build 21996 x64, although this was also occurring on Windows 10

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?
Whenever I open a file in Shotcut and put it onto the timeline, it only displays the file and nothing else, and when I try to playback the video, it’ll freeze or even sometimes stop responding.

There are several known bugs with 21.05.18.
The Recommended Stable Version is 21.03.21, and can be found here.

I am fairly sure this is the same bug as below that was already fixed for the next version 12.06 due in a couple of days:
