3. Expected behavior
I expected an al file to be created. No changes occurred in any of my code since last week, when they compiled successfully.

4. Actual behavior
The above error appeared in the Output panel. Note that it included the instruction to report the issue here.

5. Versions:

• AL Language: v15.0.1290655 (pre-release)
• Visual Studio Code: 1.96.4 (user setup)
• Business Central: v25
• List of Visual Studio Code extensions that you have installed:
• Operating System:
  • Windows
  • Linux
  • MacOS

Final Checklist

Please remember to do the following:

• Search the issue repository to ensure you are reporting a new issue

• Reproduce the issue after disabling all extensions except the AL Language extension

• Simplify your code around the issue to better isolate the problem

Remove ptecop temporarily from analyzers and it should work. I'm accepting this so we can fix it asap

[skkulla]

Removing analyzers is no help, same error

[yannstlo]

Installed VSIX 25.2 manually and it allowed me to build.
Still waiting on a fix.
Thanks

Removing analyzers on pre-release version (v15.0.1290655) from extension level .vscode/settings.json helped!
When I switched back to release version it solved the problem.

Got same error today! Setting "al.enableCodeAnalysis": false and removing "al.codeAnalyzers" entirely allowed to bypass this.
