Cannot export PDF: Export to PDF was OK but now failed with no error message

Help
1

What I’m trying to do

Export note as PDF.

This function was OK. But now I confront a problem

Things I have tried

1 execute the command export pdf,

2 use the default pdf export parameters and press export. then i select where to export the pdf

3 the progress bar shows up saying OB is preparing the pdf

4 after a while, the notification shows up saying pdf is saved to the the selected export folder

then, in the folder, there is nothing.

i checked the obaidian developer’s view, there is no errors in the console.

i have tried the sandbox vault, same result.

i also tried better export to pdf plugin, no pdf is generated. but this time, a error message is given in the console:

is there anything that i can do to look into the obsidian work flow that export the pdf, so that can help find the cause?

I think i have found the cause: the font i used in the obsidian is somehow not working well in the system level(I can see it is installed, but exporting PDF does not work).
The possible My solution maybe is:
1 reinstall the lost font
2 Within Obsidian, use a different font installed in the system as the Text font.

I will continue testing for a few days to see if this problem is really solved.

Observed a similar problem on fresh Ubuntu 24.04.3 installation (Kubuntu, obsidian-1.10.3). Export to PDF option worked well on previous Ubuntu 24.04 (older obsidian version), but stopped working after migration to the new system.

The difference with your case is that there is no notification of pdf saving to export folder

The similarity to you case is pdf file was not created after clicking the export button and choosing the export destination folder with any of the following methods: default export to pdf, better export to pdf plugin or enhanced export plugin.

Things I have tried, which did not help:

  • install different versions of obsidian: AppImage, snap, deb
  • install pandoc
  • install texlive-full
  • install miktex
  • reboot and try all of the Export to PDF methods again

Thing that solved the problem:
Install random older version of obsidian .deb package (obsidian_1.7.4_amd64.deb).
After the installation Obsidian shows that the app version: 1.10.3, installer version: 1.7.4.
And, finally: default Export to PDF works, better export to PDF plugin works,
Enhanced Export still does not work (which is not a problem for me, since at least one method works)

Note (probably for Obsidian developers):
For me, a small difference in style of “Save File” window exists before and after fixing the export to PDF function. This system window always appears after clicking “Export” button. But when PDF was not created, the “Save File” window was smaller in size. Which makes me think it utilized some other routine of file saving for both default Export to PDF function and Better Export to PDF plugin.

Some things which help me might be helpful:

  1. I open the obsidian with only the sandbox vault opened, and this time, the export to pdf works, this gives me confidence that the problem may be related to the configuration.
  2. The order may be important: if i try to export pdf within my other vaults(which have fonts customization) first and it is failed, then, when i try to open a new sandbox vault or switch to the opened sandbox vault, without closing and reopening the entire obsidian, the export will also be failed in the sandbox vault.
  3. I install the typora, which uses electron framework as well, and it can export pdf successfully. This provides me the information that the system/workflow is probably not broken.
