Proget: Extension Loader -> Error initializing extensions manager.

Hi,
We recive some errors from the extension-loader. :

Error:
System.Text.Json.JsonException: '0x00' is an invalid start of a value. Path: $ | LineNumber: 0 | BytePositionInLine: 0.
---> System.Text.Json.JsonReaderException: '0x00' is an invalid start of a value. LineNumber: 0 | BytePositionInLine: 0.

Does anyone else got this error?
We have installed only one extension: Inedo.SDK 2.3.0

ProGet-Version: Version 2023.19 (Build 16)

Does anyone have some advice here ?

Hi @A-Schoder_7166 ,

It sounds like your installation is somehow corrupt?? I can't imagine what would cause that error but it's basically saying that the upack.json file within the extension file (xxx.upack) is corrupt.

Maybe some antivirus tool went and "quarantined" zip files on disk that contained executable code? Really hard to guess. The file sare loaded , typically in c:\Program Files\ProGet\Extensions, and they are part of the installation.

I would uninstall and reinstall, and hopefully that will fix the issue.

Thanks,
Alana
