When I knit to pdf, I get a pop up that says "The code execution cannot proceed because luatex.dll was not found. Reinstalling the program may fix this problem." I click OK, then I get this output:

This is pdfTeX, Version 3.14159265-2.6-1.40.21 (TeX Live 2020/W32TeX) (preloaded format=pdflatex) restricted \write18 enabled. Running the command C:\Users\Ryan.M.Allen\AppData\Roaming\TinyTeX\bin\win32\fmtutil-user.exe

I can't find the format file `pdflatex.fmt'!

kpathsea: Running mktexfmt pdflatex.fmt

The command name is C:\Users\Ryan.M.Allen\AppData\Roaming\TinyTeX\bin\win32\mktexfmt I was unable to find any missing LaTeX packages from the error log BA_LunchLearn.log. ! Running the command C:\Users\Ryan.M.Allen\AppData\Roaming\TinyTeX\bin\win32\fmtutil-user.exe

! kpathsea: Running mktexfmt pdflatex.fmt

! The command name is C:\Users\Ryan.M.Allen\AppData\Roaming\TinyTeX\bin\win32\mktexfmt

Error: LaTeX failed to compile BA_LunchLearn.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See BA_LunchLearn.log for more info. In addition: Warning message: package 'corrplot' was built under R version 3.6.3 Execution halted

I have tried uninstalling tinytex and reinstalling it and then restarting Rstudio each time. I also get the output of TRUE when I run the command tinytex:::is_tinytex(). So I think it is on my machine but the pdf knit does not work.
