About 100 G on a 500 G partition. I would only like to recover some

I don't need the partition to be mountable again.

I had to install FreeBSD on that disk (with Linux, a btrfs partition,
and several free partitions on it).
When using the FreeBSD partition tool, I didn't create or delete any
partitions. I only assigned a
free partition to FreeBSD. When I booted later in Linux the Btrfs
partition did not mount anymore.

btrfcsk -s 2 exits with:
using SB copy 2, bytenr 274877906944
No valid Btrfs found on /dev/sda10
