P: The "create new" window shows up blank, how do I fix this issue without using legacy mode?

[FeedbackCommunityMember]

After updating to PS 2020 the "create new" window has been broken. I have both a MacBook Pro 2018 and a fully updated Windows stationery PC with Photoshop 2020 and I have this issue on both. I've tried to reinstall, turn my PC on and off, reset preferences, and nothing works. I know you can just use the legacy interface mode, but I would like to still see this issue be fixed.   I really hope this will be fixed, because until it is I don't really see myself using PS that much, which is annoying...
