Runs correctly in xtb 6.7 (xtb input.xyz -I xtbinput)

To Reproduce
crest input.toml

input.toml

input = "input.xyz"
runtype = "optimize"
constraints = "xtbinput"

xtbinput

$constrain
    force constant=2
    distance: 2, 3, auto
    reference=ref_coord.xyz
$end

input.xyz/ref_coord.xyz (a stretched butane molecule)

which 3.0.2, a prebuilt binary from GitHub, the conda version, or self-built?

[pprcht]

Ah, sorry it's conda, I can see from the error backtrace.
The fix for this issue was already uploaded in commit 5ca82fe, but since the conda version is not built from the main branch, it will not be updated until the next manual conda update (i.e. 3.0.3).
