Maybe. But as you may know, I’m new to this. 2 1/2 yrs ago I configured a pc specifically to attempt an eOS build. Found it too daunting. I’m having another go now and I’ve been at for a week. didn’t have much hair in the first place but with all the head scratching…well. Anyway.
Building for bluejay pixel 6a I had the same error and got past it by copying "//external/rsync",to the file ~/android/lineage/external/zstd/Android.bp at line 52 ish.
It was all I could think of, and it may be part of my current errors; I don’t know.
