Being the person who last regenerated McLachlan for the last ET
release: I just gave this a try with 12.0.0 on Linux and there at least

env ML_CODE=BSSN ./runmath.sh McLachlan_BSSN.m McLachlan_BSSN


I will update to 12.2.1 and see what happens. If that fails then at
least we know that we can check Wolframs docs do see what they
functionality they removed to make this fail.
