Server crashes involving plan_cache_mode

[dpxcc]

What happens?

Server crashes when executing the script below involving plan_cache_mode
The repro below is somewhat minimal that removing any query in it doesn't crash

To Reproduce

SET duckdb.force_execution = ON;
CREATE TABLE t (a INT);
PREPARE f (INT) AS SELECT count(*) FROM t WHERE a = $1;
SET plan_cache_mode TO force_generic_plan;
EXPLAIN (COSTS OFF) EXECUTE f(2);
EXECUTE f(1); -- crash
