Are you developing remotely, e.g. over SSH or in a docker container?

Generally speaking, I need a lot more information than you gave me to diagnose the issue since I'm not experiencing any problems.

I work on a local Computer, the data is saved in an in-house server, but all programming is done on a desktop, all Programs and the Extension in question are installed locally on the system hard drive.

I'm using VS Code 1.86.2

Hmm. I'm not sure what to make of this. There was only one commit (9145b45) between 1.17 and 1.18. It could be the source of your issue, but I personally use my extension in every configuration I can imagine:

• Fully local
• Remote over SSH
• "Remote" to a docker container
• Via a server like vscode.dev

v1.18 works for me on all of these.

Could you list your other installed extensions (code --list-extensions --show-versions)?

Also, are you able to reproduce with a clean install of VSCode (e.g. on a second computer)?

Here is the List:
