Object Reference not set to an instance of an object in Microsoft Visual Studio Fix

Some Microsoft Visual Studio users have reported an error message “Object reference not set to an instance of an object.” while opening several projects. Though at first sight, it may feel like other installations (like ASP.NET or Web Tools) may have affected it, the corrupted local cache of VS is actually the main culprit here. So, just follow our instructions and get Visual Studio back in no time at all.

Fix 1 – Delete the local VS cache

Delete the Local VS cache from your system. You can do it directly from the terminal or using the GUI (File Explorer).

Step 1 –

NOTE – As you are removing the local cache and resetting the user setting to default, expect all the personal changes you have made under VS Layout, and linked MS account to be gone.

1. Before you do anything, close the Visual Studio app.

2. Then, open File Explorer on your computer.

3. Next, go to this location –



4. Here, select all the components inside and tap the bin icon to empty the folder.

5. Now, head on to this point –



6. After that, press the Ctrl+A keys together to select everything at once.

7. Finally, tap the “Delete” key from your keyboard to remove all the components.

Close the File Explorer.


Step 2 –  Reset the userdata

This step is optional and only if Step 1 alone doesn’t fix the issue, do this.

You can easily reset the user data using a terminal.

1. Type “cmd” in the search box.

2. Then, right-tap the “Command Prompt” that appears in the search box and tap “Run as administrator“.

3. After that, you have to go inside the Visual Studio installation folder using the cd command.

x64 system - C:\Program Files (x86)\Microsoft Visual Studio 22.0\Common7\IDE
x86 system - C:\Program Files\Microsoft Visual Studio 22.0\Common7\IDE


So, the command is –

cd installation folder of VS

You have to replace the “location of VS” with the installation folder on your computer.

cd C:\Program Files (x86)\Microsoft Visual Studio 22.0\Common7\IDE


Ide Cd


4. Finally, execute this to reset the userdata.

devenv /resetuserdata


Devenv Reset Userdata


After this, close the terminal and relaunch the Visual Studio. Check if this works.


Fix 2 – Restart VS

This Object reference issue you are having may just be a one-time glitch. Just close Visual Studio processes and test.

1. If you right-click the Windows icon, you will notice the context menu.

2. There, tap “Task Manager” to open that.

3. On the Task Manager panel, look for the “vshub.exe” process.

After this, restart Visual Studio.

Check if this helps. You won’t see the “Object reference not set to an instance of an object ” error message again.

There is another way of doing this. You can install the Clear MEF Component Cache extension and use it to do the same.


Fix 4 – Run Visual Studio as an administrator

Fix 5 – Manually reset the VS User data

2. There, click on “Tools>” and click on “Import and Export Settings” to open that setting.

This process takes just a few seconds.

Finally, tap “Finish” to complete the process.

Once all these are done, open the project once more and test it.

2. Then, click on “Tools” and tap “Get tools and features” from the drop-down list.

6. Finally, when you are satisfied with your selection, tap “Modify“.


Modify Tools All Min


Wait for Visual Studio Installer to install the packages. Then, close and relaunch VS once and test further.

The problem won’t resurface again.


Fix 9 – Disable the Touch service

If you are working on a Surface device or any touchscreen device, the Touch Keyboard and Handwriting Panel Service can cause the problem. Disable it on your system.

1. At first, open a Run box using the Win key and the R key.

2. Then, write this down and hit Enter.

Close Services after this. Open the Visual Studio and test.


Fix 10 – Check your code once more

If all these solutions have failed to fix the problem, you should review the code for any issues such as having a reference object with a null value. This can create such instances and you should omit those mistakes and try again.

Additional Points

Though this problem usually appears in Microsoft Visual Studio, in some cases, the same error message may appear while using AutoDesk Vault. In that case, you can just uninstall the Autodesk Vault from your system and reinstall it.
