I created a scratch org with the new Winter release.
After pushing my code without trouble, and updated it, I wanted to pull it to local files using :
sfdx force:source:pull --forceoverwrite -u myScratch
Now this error showed up :
ERROR: Metadata API received improper input. Please ensure file name and capitalization is correct. Load of metadata from db failed for metadata of type:AppMenu and file name:AppSwitcher.
Thing is, push works and I haven't modified an App.
Also note that it worked on a older scratch with Summer release.
I'll take any idea or advice.
Thank you for helping.
