Error : File `l3backend-pdfmode.def' not found. }

Question

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
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 Jachetta

I had the same problem, turned out my miktex library was out-of-date

I opened "miktex console" and updated it.
