Anacronik: sorry for the delay to reply back to your post: This is the answer I got from their support team @ supportbg3@larian.com
Please reply with your latest save in camp, just before resting (or a Dropbox or Google drive link, etc).
Each save is a folder in the '..\Documents\Larian Studios\Baldur's Gate 3\PlayerProfiles\<ProfileName>\Savegames\Story' folder.
In Windows Explorer you can zip a file or folder by right clicking on it/them and selecting 'Send To | Compressed (zipped) Folder'.
This is a known issue (that can be triggered if a character dies during the attack on the druid grove), which will be fixed in a future update.
Cheers,
D
