RStudio IDE
1

I am reporting a critical compatibility issue between RStudio and Windows 11 24H2 (Build 26120.3360) that requires urgent investigation. Below are the detailed technical observations:

1. Problem Description

After upgrading to Windows 11 24H2 (OS Build 26120.3360), RStudio (Version: both the latest and older versions) exhibits the following failures:

  • Failure to Launch: Task Manager confirms that there is an instance of “rstudio.exe”.
  • R Environment Disconnection: Cannot detect locally installed R interpreters (v4.* and v3.*), though both run independently via RGui/Rterm.

Reproducibility: 100% consistent post-update.

2. Troubleshooting Performed

  • :white_check_mark: Validated R/RStudio version compatibility (Confirmed via RStudio documentation)
  • :white_check_mark: Disabled firewall/antivirus (Windows Defender & third-party tools)
  • :white_check_mark: Tested admin privileges and clean-boot mode
  • :white_check_mark: Reinstalled RStudio
  • :white_check_mark: Verified R_HOME and PATH variables (where R in CMD returns valid paths)
  • :white_check_mark: Checked dependency libraries (MSVC 2019-2022 Redistributable v14.38.33135.0)

3. System Environment

Component Details
OS Windows 11 24H2 (26120.3360)
CPU ntel(R) Core(TM) i5-8265U CPU @ 1.60GHz (1.80 GHz)
R Versions V4.& V3.

I appreciate your prompt attention to this blocking issue.

Apologies did not read fully "Tested admin privileges and clean-boot mode"

Assuming now that you have "run as admin".

Yes, run as admin. Also tested pure scenarios with antivirus software and system protection wall turned off.
