--- Comment #2 from Huanyu Liu <1293660...@qq.com> ---
First, I tried the Flatpak version of Nightly Build 8e9ceb4 (May 23 2024,
15:19:10) and encountered a more serious problem: the Import Data from File
feature is completely unusable. A message "Failed to open the device/file of
it's empty." is shown when attempting to import. This happens even if I give
LabPlot the filesystem permission `--filesystem=host`. I'm not sure whether I
didn't have something configured correctly. Here is the debug message printed
to the terminal:

Then I tried the AppImage version of Nightly Build f17356b (May 19 2024,
10:37:08). Import Data from File works fine, but the crash can still be
triggered.
