I have several errors on my BTRFS partition (SSD -> luks -> BTRFS):

btrfs check --check-data-csum -p --force /dev/mapper/sda3_crypt
...
mirror 0 bytenr 1337316519936 csum 850178701 expected csum 2442214357
mirror 1 bytenr 1337316519936 csum 850178701 expected csum 2442214357
mirror 1 bytenr 1337316524032 csum 3411875857 expected csum 208994536

I'd like to know which files are affected but there are no inodes given.

Is there a way to resolve the listed bytenr values to an actual file path?

To resolve the bytenr use the following command:

btrfs inspect-internal logical-resolve <bytenr> <path>

where <path> should point to the BTRFS top-level subvolume to be able to list the affected files in all snapshots (one bytenr may be linked by a file that exists in several snapshots).

Example:

mkdir /mnt/btrfs-root
mount -t btrfs -o subvolid=5 /dev/sda2 /mnt/btrfs-root

btrfs inspect-internal logical-resolve 1337316519936 /mnt/btrfs-root

umount /mnt/btrfs-root && rmdir /mnt/btrfs-root

Please note: subvolid=5 will mount the "BTRFS root" (or top-level subvolume). A freshly created filesystem is also a subvolume, called top-level, internally has an id 5. (Kernel.org)
