Delphi FireMonkey+Zeoslib下SQLite3的VACUUM INTO等SQL突然报错

我用Delphi FireMonkey开发的应用，通过Zeoslib 8.0集成SQLite3数据库，将其作为项目状态容器而非常规数据库使用。为实现自动撤销功能，创建了大量触发器，示例如下：

CREATE TRIGGER Timepoints_BeforeUpdate BEFORE UPDATE ON TimePoints 
 FOR EACH ROW
   BEGIN
      INSERT INTO UndoTable(UndoGroupID, UndoEventType, SQLText)
      VALUES(-1,3,"UPDATE TimePoints SET 
      TimePointID="||quote(old.TimePointID)||", FrameID="||quote(old.FrameID)||",
      TimelineID="||quote(old.TimelineID)||", TimePointInMS="||quote(old.TimePointInMS)||", 
      CameraInstanceID="||quote(old.CameraInstanceID)||", BinaryWorld="||quote(old.BinaryWorld)||", 
      HoldTimeInMS="||quote(old.HoldTimeInMS)||", IsWayPoint="||quote(old.IsWayPoint)||"
      WHERE TimePointID = "||new.TimePointID);
    END

近期原本正常的SQL语句在应用中突然报错，但在数据库管理器中执行完全正常。例如以下语句：

VACUUM INTO "C:\Users\Support\AppData\Local\Temp\previs.vac"

应用报错信息：

SQL Error: SQL logic error or missing database
Message : near "INTO": syntax error
Code: 1 SQL: VACUUM INTO "C:\Users\Support\AppData\Local\Temp\previs.vac";

此前也曾遇到INSERT INTO ... ON CONFLICT语句报类似语法错误，移除触发器后问题解决，但此次已验证目标目录存在、目标文件不存在，仍无法解决VACUUM INTO的报错问题，求相关排查思路。
