RStudio hangs and won't run any code

[itsdanwall]

RStudio Edition : Desktop or Server 
RStudio Version : 1.2.1244
OS Version        : Windows 10
R Version          :  3.5.2

I am running an R script in RStudio. Everything works fine for a few minutes but then I can't run any code, save my file, or close out of RStudio other than via Task Manager. The console does not run any code; however, I can edit the script.
This behavior happened in my old version of RStudio. It happens for RMD files as well.

I've removed all non-essential objects from my workspace; reduced the number of packages loaded.

Steps to reproduce the problem

Just an update on this. As suggested at #2141 I removed the .git folder from the project. This didn't work. I also updated to the latest release version of RStudio, which also didn't work. I also ran the script outside of the project and the behavior persisted. I deleted the .Rproj file and created a new one (As suggested here: https://support.rstudio.com/hc/en-us/community/posts/214993747-Rstudio-crashes-freezes-when-I-try-to-open-an-R-project).

I'm not sure what else to do.

Thanks!
