It is a bug in Flare 2021R3.
Here's what you can do.
ONLY FOLLOW THESE STEPS IF YOU HAVE BOUND GIT AT A HIGHER LEVEL FOLDER THAN THE FLARE PROJECT FILE.Open the files in Windows Explorer, and open the folder where your Flare flprj file lives (your Flare project file).
Flare added files here, but you may have to use View > Show hidden files in Windows Explorer to see them.
You need to delete the .git folder. You need to delete the .gitignore file. If you see any further .git files, you can delete them too.
Now, roll back to Flare 2021
R2. If you need the download again, you should be able to get it (with your license key) here:
https://www.madcapsoftware.com/download ... -products/.
I hope MadCap will release a patch soon, but in the mean time, the only thing I've found that works is rolling back to 2021 R2.
