Bug with xml files as clip

What is your operating system?

I use windows 10 and the last version of shotcut (23 05)…
I have created a file and saved in XML but it is impossible to use this file in another file (with "open as …).

I succeeded with difficulty to put this file at the beginning of my video but when I must read the file, shotcut crashes…


Do you have GPU Effects turned on?

If not, then what is the video mode of each project?

I don’t use GPU.
I use proxis and view to 540p.
