--- Comment #11 from Ben Jackson benjackson990@gmail.com --- 'FUSION_IDSDK=false' is dead in the water, after Autodesk rebranded and cleaned out the legacy login mode
However the change made in Wine 8.14 indeed has worked, and we are now able to login to Fusion (No-longer Fusion 360) via the Web browser SSO
Thank you Piotr Caban for all your work, its really appreciated.
I believe this bug is fully resolved, as the product is now working as expected thanks to the PR in Wine versions upwards of 8.14
