ktrace shows that dup(0) succeeded but fstat(0) failed. The symptom is the same as in #30225. Could you check whether any of the following quick tests produces the same error?

python3 -c 'import os, subprocess, sys; r, w = os.pipe(); os.close(w);[sys.executable, "-c", ""], stdin=r)'

python3 -c 'import os, subprocess, sys; r, w = os.pipe(); os.close(r);[sys.executable, "-c", ""], stdin=w)'
