Whenever I try to knit on R I get this error

Error: LaTeX failed to compile rmkdfile.tex. See The R package tinytex - Helper Functions to Manage TinyTeX, and Compile LaTeX Documents - Yihui Xie | 谢益辉 for debugging tips. See rmkdfile.log for more info.
In addition: Warning message:

No LaTeX installation detected (LaTeX is required to create PDF output). You should install a LaTeX distribution for your platform: Get LaTeX - Mac OS, Windows, Linux

The last paragraph tells you all. Therefore install a LaTeX version.

I have the tinytex package installed and loaded, I have tried restarting but I still get the same error

[HanOostdijk]

Then it looks like the LaTeX install has not been done correctly.
I can't help you with that.
For other forum members to be able to help you it is necessary to specify the details of your R environment.
E.g. share the result of sessionInfo after loading rmarkdown :

library(rmarkdown) 
sessionInfo()

Good luck!

I have the tinytex package installed and loaded,

The error message refers to a LaTeX distribution (like TinyTeX) not to the tinytex package, besides installing the package, you need to install the TinyTex LaTeX distribution, you can do it with this command:

tinytex::install_tinytex()

Documentation about install LaTeX using TinyTeX distribution through tinytex package is there:
