Hi,
@tjmahr
How is this fix holding up for you? I'm struggling with the same random RStudio lag problem. It wasn't clear to me from your reply whether the fix continued to work or not. If it is still working, could you specify where to find the R and github exe files you added to Windows Defender exclusions? Also, did you have to restart RStudio and/or the computer before the changes took effect?
Thanks very much for your help with this.
