Attempting backtrace. You can use the following information to find out

Hello Libing,

Thank you for the report and feedback.
Observed that 8.0.16 debug build is affected.

Minimized testcase from Jon Olav:

CREATE TABLE t1(col1 TEXT AS (Upper("Assert")));
INSERT INTO t1 VALUES ();
DELETE FROM t1;

There is no assert on 5.7.
