I am trying to compile a .tex document into a pdf in TexStudio (and I have also tried in MikTex) and the following error is outputted File l3backend-pdfmode.def not found
. I have tried downloading 13backend package but no luck. Do I need to place the package in a specific folder?

Can you add a small test document that reproduces the error and the .log file? – samcarter_is_at_topanswers.xyz Jul 08 '19 at 14:55

Just a note, I found this error while using Rstudio and Rmarkdown, but I used `tinytex::reinstall_tinytex()` as suggested in the error messages I got in the console and it worked for me. – Daniel_j_iii Oct 30 '20 at 14:41

I had the same problem, turned out my miktex library was out-of-date
I opened "miktex console" and updated it.

I incurred into the same issue slightly after an upgrade from Debian 10 to Debian 11. For me, removing all the .texlive*
directories from my home folder solved it
mv ~/.texlive* /tmp # If you want to restore them later
rm -r ~/.texlive* # If you are sure about deleting
The ~/.texlive2020
directory was rebuilt after running pdflatex
.
