Hi wuciw, It looks like a Windows update error. First make sure your Windows updates are all completed and up to date. If that didn't solve your problem, here is an article I found that might be helpful to you: https://techdows.com/2019/01/windows-10-build-18309-showing-bindflt-sys-failed-green-screen-error.html If it still doesn't work, please submit a ticket to our support: https://www.reallusion.com/CustomerSupport/UserEx/QForm.html Hope your issue can be solved soon.
