While there is no single official Adobe "fix" for every UXP Developer Tool (UDT) issue, community-led projects and manual troubleshooting steps have resolved the most common "broken" states: Community "Fixed" CLI
Third-party developers have released patched versions of the official command-line tools to resolve persistent installation and connection bugs: uxp-toolkit : This toolkit includes a fixed CLI for UXP
that addresses common issues found in the official Adobe package [11, 15]. @adobe-fixed-uxp/uxp-devtools-cli
: A community-maintained version of the CLI that fixes installation failures and enables commands like uxp plugin debug on Mac [7]. Manual Fixes for Common Errors
If you are experiencing specific bugs in the official standalone GUI tool, these manual steps often resolve them: Hidden Console/Debug Messages adobe uxp developer tools fixed
: If the debugger window is blank or logs are missing, close the tool and Photoshop, then navigate to your local AppData folder ( %APPDATA%/Adobe UXP Developer Tools ) and delete the Local Storage Session Storage preferences "No Applications Connected" Error Enable Developer Mode
: Ensure "Enable Developer Mode" is checked in both the UXP Developer Tool settings and the host application (e.g., Photoshop > Preferences > Plugins) [16, 17]. Manual Settings
: If the tool fails to enable developer mode, manually create a settings.json file containing "developer": true in the Adobe UXP Developer folder ( /Library/Application Support/Adobe/UXP/Developer %CommonProgramFiles%/Adobe/UXP/Developer on Windows) [8]. Plugin Not Appearing
: If the tool says the plugin is loaded but it isn't visible, check the While there is no single official Adobe "fix"

For a stable development environment, Adobe recommends using the latest versions from their developer portal: UXP Developer Tool

In theory, UDT offered "Hot Reload" for manifest changes and UI updates. In practice, developers reported that after 3-4 reloads, the plugin would freeze, forcing a full restart of the host application (e.g., Photoshop). This made iterative UI design a 45-minute ordeal for what should have been a 5-minute task.
Currently, debugging UXP plugins involves relying heavily on console.log, manual element inspection, and guesswork when UI elements don’t behave as expected. There’s no visual way to inspect the UXP DOM, view real-time style changes, or see layout boundaries — making UI debugging slow and frustrating.
The uxp package command now produces a .ccx file that passes Adobe’s marketplace checks on the first try. No more manual zip renaming or missing icon errors.

This new flag checks for orphaned event listeners and memory leaks—things the old tools missed.
With the stability crisis averted, Adobe has announced the next phase for UDT in Q3/Q4 2024:
