Cannot Open Modified Files from Amazon Q Chat – “Editor Could Not Open” Error

[suhail-edstem]

Problem

I’m experiencing an issue with the Amazon Q extension in VS Code where I am unable to open modified files directly from the Amazon Q chat interface. When I click on a file that has been modified (e.g., through a code suggestion or diff), I get the following error:

"The editor could not be opened due to an unexpected error."

However, the same file can be opened manually through the Explorer or using the Command Palette, so the file path itself seems valid. The issue appears to be specific to Amazon Q's mechanism for opening the file.

This makes it difficult to quickly review or accept code changes suggested by the assistant.

Steps to reproduce the issue

Ask Amazon Q to suggest or modify code in a file.

In the Amazon Q chat panel, click on the modified file shown in the results.

Observe the error:

"The editor could not be opened due to an unexpected error."

Manually open the same file through VS Code Explorer – works fine.

Expected behavior

Clicking on a modified file from Amazon Q chat should open it in the editor without errors.

fix for the issue: #8047. Releasing this Thursday in next update. Please use version 1.93.0 for now to mitigate. Version 1.95.0 should have the fix

I fixed without switching versions by doing this:-

Go to:
C:\Users\hp\AppData\Roaming\Code\User\workspaceStorage

Delete all the folders inside (workspaceStorage). (Don’t worry, VS Code will recreate what it needs when you reopen your projects.)
