RStudio启动后自动运行未知进程致CPU占满，面板空白求助

I've run into a nearly identical problem before, so here are some practical, tested solutions based on my own experience and community fixes:

1. Clear RStudio's Cache & Configuration Files #

• First, fully shut down RStudio—don't just close the window, use your system's task manager/activity monitor to end all rsession processes running in the background.
• Locate RStudio's configuration folder:
  • Windows: %APPDATA%\RStudio
  • macOS: ~/Library/Application Support/RStudio
  • Linux: ~/.config/rstudio
• Rename this folder (e.g., to RStudio_backup) and restart RStudio. It will automatically generate a fresh set of default config files. Check if the high-CPU issue goes away.

2. Skip R Startup Scripts to Test a Clean Session #

• Sometimes rogue code in .Rprofile or .Renviron can trigger infinite loops or hidden processes on launch.
• Launch RStudio while holding Ctrl+Shift+F10 (Windows/Linux) or Cmd+Shift+F10 (macOS)—this skips loading all startup scripts and opens a completely clean session.
• If RStudio works normally this way, dig into your .Rprofile (usually in your user home folder or current working directory) and .Renviron files to find and remove any suspicious code (like unending loops, recursive functions, or calls to external processes).

3. Verify R Works Independently of RStudio #

• Open R directly (not through RStudio) and check if it runs without auto-executing any strange processes.
• If R itself has issues, reinstall R 3.6.1 to rule out corruption in the R installation. If R runs fine standalone, the problem is definitely tied to RStudio's setup.

4. Disable RStudio Plugins #

• Outdated or conflicting plugins are a common culprit for this kind of behavior.
• Launch RStudio with the --disable-plugins parameter:
  • On Windows, right-click the RStudio shortcut, edit the target field to add the parameter, e.g., "C:\Program Files\RStudio\bin\rstudio.exe" --disable-plugins
• If the issue disappears, re-enable plugins one by one to pinpoint which one is causing the conflict.

5. Update/Downgrade RStudio (Stick to Compatibility) #

• Your RStudio version 1.2.5019 is quite old, and while it's technically compatible with R 3.6.1, there are known stability bugs in early 1.2 builds.
• Try upgrading to the final stable release of the 1.2 series (1.2.5033) or a compatible newer version (note: R 3.6.1 only supports up to RStudio 1.4.x—newer versions won't work with it).
