This was intentional change to prevent issues with backup tools and cloud storage apps messing up with Playnite files, which started to be serious issue. The only solution is to use backup app that supports use of shadow copies which can be used to copy locked files. Or as you say, close Playnite before copying files.
Lastly, I do plan to add some backup option to Playnite in future https://github.com/JosefNemec/Playnite/issues/912
