After I installed Mac OS Big Sur, the RStudio Desktop files pane would no longer open .pdf files or allow me to view .html files in the web browser. I can open .Rmd, .R and even .html files in the editor.
I upgraded to RStudio desktop Version 1.4.1048 , but that did not work either.
Appreciate any suggestions to re-enable the capability.

Not an answer, but I have the same problem. I can't start R Studio, because it always will tell me, that Rstudio failed to start. No errors are reported. I already deinstalled and reinstalled RStudio and R as well as reinstalling MacOc Big Sur. No changes.

Not an answer either. I don't use MacOS but I have seen many posts both here (rstudio community) and on reddit about problems with R studio on MacOS big sur. One "fix" to these problems is apparently to use Time Machine when updating, as they talk about in this related topic: Rstudio on macOS Big Sur?
Hope this is helpful

I would recommend filing an issue here: Issues · rstudio/rstudio · GitHub
It may also be helpful to know if you've registered a default viewer for PDF files (e.g. Adobe Reader rather than Preview, or something else).

Thanks to all. Someone filed a similar issue last night (https://github.com/rstudio/rstudio/issues/8506) so I added my comments to it.

p.s. I use preview as the default viewer for PDF.
I have the same issue but a screen pops up asking if I want to retry. I click the button to do so and it starts then,
Daily build 1.4.1076 has a fix, as of three hours ago.
