Same problem in 0.20.28:
lf = pl.LazyFrame({
"duration": [1000, 2000, 3000]
}, schema={"duration": pl.Duration})
print(lf.select(pl.col('duration').min()).collect())
thread '<unnamed>' panicked at crates/polars-core/src/datatypes/any_value.rs:811:19:

Might this be the bug?

Lines 407 to 414 in 24b77de
.as_duration()
is called twice.
from polars.
Or perhaps AnyValue::as_duration()
should just be fixed to handle the case where self
is already AnyValue::Duration
