A very annoying bug in AutoCAD in recent versions (2018-2023) manifests when double-clicking on text to edit, causing AutoCAD to freeze for a long time or even crash. This issue occurs with all types of text and all toolsets related to text.

I have tried every troubleshooting method suggested by Autodesk, but none have been successful. This includes updating Windows, updating the GPU driver, removing all lisp files on startup, running PURGE and AUDIT, using default fonts, and even reinstalling AutoCAD.

Ultimately, I discovered that the real cause was a corrupted .NET library. AutoCAD still uses .NET Framework 3, and during the Windows update, some files from this library were overwritten or changed. This made AutoCAD very prone to conflicts and freezing when interacting with text.

How to Fix

First, download .NET Core 3.1.10 to your computer. After extracting, you will find two files:

• dotnet-runtime-3.1.10-win-x64.exe
• aspnetcore-runtime-3.1.10-win-x64.exe

We will need to use both files for the installation. My recommendation is to completely uninstall the old version (Uninstall) and then reinstall it (Install) instead of using the repair option (Repair).

First, close AutoCAD, then run dotnet-runtime-3.1.10-win-x64.exe as an administrator (Run as Administrator). Click Uninstall (1) to remove the old .NET library. Do the same with aspnetcore-runtime-3.1.10-win-x64.exe. Run it as an administrator and click Uninstall again. Once this is done, proceed to run both files again in order. Click Install (2) to complete the installation.

Typically, this solution will take effect immediately without needing to restart your computer. Open AutoCAD and try editing a text object to test if the issue has been resolved.
