ClickHouse: Clickhouse Update mutation randomly stucks

I’m trying to update some values (no distribution) (table size 300Gb)

ClickHouse server version 19.13.2 revision 54425.

alter table actions
 UPDATE quality = 'val' WHERE (category = 'account') AND (name = 'true_buy') AND (quality = '') 

I’m getting at random parts.

Am I missing something?
