Was unsure which product to choose since you don't have one specifically for plasma-desktop, so feel free to move this appropriately.

It builds fine for me and on our CI, which means this is a local issue on your system. Bugzilla isn't the place to ask for help with build issues; I'd recommend getting in touch using one of these methods: https://community.kde.org/Get_Involved/development#Where_to_find_the_development_team
See https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/2833
Oh! I guess it is a real issue then.

So for maybe asking a stupid question. This bug is fixed in the current 6.3.1 tarball or is it necessary to apply the patch manually?
6.3.1.1 is out which fixes this, so that answers my question^^
