I have server mariadb-10.5.16 with slave_parallel_mode=optimistic and see errors in log:
```
2024-01-24 8:00:46 57 [ERROR] mysqld: Can't find record in 'test'
2024-01-24 10:40:55 56 [ERROR] mysqld: Can't find record in 'test'

2024-01-24 15:33:25 57 [ERROR] mysqld: Can't find record in 'test'
```

how to repeat:
```
drop database if exists my_table_test;
create database if not exists my_table_test;
use my_table_test;
drop table if exists test;
create table test(a int, b varchar(123));
insert into test values(1, 'asdf');
update test set b='zxf1' where a=1;
update test set b='\n' where a=1;
```

Replication is not crash and still works.
