@vrunk11 it would help to know how you installed your copy of Theia and exactly how you installed the plugin.

Also: is there anything in the browser or console log?

here a log of the dev console after startup
-1683297946738.log

i installed the extension using "install from .vsix ..." inside the ide

i installed Theia IDE using the blueprint installer and using the "for me only" install mode

side note : when getting that bug even uninstalling and removing all file the reinstall didn't seem to fix the issue (using the same extension as before) , but on a fresh install it works fine using a VM and the same .vsix

also note that Somme of the extension reappeared but I still have 4 missing (they are in the folder but not in the ide)

another interesting things to note is that some extension seem to disappear if i disconnect internet then launch theia but reaper if i reconnect internet and launch the IDE 🤔

Hi @vrunk11 ,

That's strange. Did you notice if the extensions were among those you had installed yourself or extensions that come pre-packaged with Blueprint? (like several Java-related extensions).

On Windows, Blueprint currently unzips user-installed extensions under the temp folder, usually:
C:\Users\<Username>\AppData\Local\Temp\vscode-unpacked\. Can you confirm if you see an unzipped version of your installed extensions, under that folder? Given the symptoms described, I wonder if they might be installed under C:\Users\<Username>\AppData\Roaming\Temp\vscode-unpacked\ instead? If you see folders with your extension's names, can you confirm the content? For each extension, there should be an "extension" folder under, that contains the bundled version of the extension. You can compare with the .vsix file, opened as a zip file.

Also, I wanted to mention that a couple of bugs (unrelated, AFAIK, to this issue here), that I see in your log, should no longer be present with the latest version of Blueprint.
