With my Huawei Nova, I could always record great videos in slow motion and save them without any problems but for some time, when I want to save the file, I'm told that the slow motion file could not be saved. Who knows why this could be?

If anyone could know, it is you. We have 0 information about the problem case, except for "does not work".
i have the same issue.
I have an issue where the newer update of the huawei video app does not have the option to save the slow mo file as well as the controller to edit which part of the video will be slowed. So i uninstalled the updates and went back to the factory version then the controls are back. I can now also save slow motion videos.
