RStudio crashes when rendering plot using Cairo backend in Windows 10

[bas]

I recently updated R to v 4.1.0. Since then RStudio crashes whenever trying to display a plot using the Cairo backend (ie in Tools > Global Options > General > Graphics). Plots work fine if I change the backend to default or Windows or AGG.

I have tried uninstalling all versions of R, rtools, and RStudio, deleting all packages, and reinstalling, but the issue remains.

I've very confused and the error message doesn't give me much to go on. Any advice would be much appreciated. Thanks.

# causes crash
library(ggplot2)
ggplot(mtcars, aes(mpg, qsec)) +
  geom_point()

# Crash message is:
# R Session Aborted
# R Encountered a fatal error
# The session was terminated

Details from the RStudio logs, but there are loads of this error going back months and I don't think it's related:

ERROR system error 10053 (An established connection was aborted by the software in your host machine) [request-uri: /events/get_events]; OCCURRED AT void __cdecl rstudio::session::HttpConnectionImpl::sendResponse(const class rstudio::core::http::Response &) src/cpp/session/http/SessionWin32HttpConnectionListener.cpp:113; LOGGED FROM: void __cdecl rstudio::session::HttpConnectionImpl::sendResponse(const class rstudio::core::http::Response &) src/cpp/session/http/SessionWin32HttpConnectionListener.cpp:118

Updating to the preview of RStudio seems to have fixed the problem. I went into windows debugger and there was something about a null pointer exception trying to point to winCairo.dll, but I was a bit out of my depth.
