vue el-from校验成功但是 return不管用？

async handleSubmit() {
      const flag = await this.$refs.form.validate().catch((e) => e)
      if (!flag) return
      this.loading = true
      try {
        await queryVipStandardEdit({
          ...this.form,
        })
        this.$message.success(this.$t('pls_operate_successful') + '！')
        this.close('success', true)
      } catch (error) {
        this.$message.error(error)
      } finally {
        this.loading = false
      }
    },

校验生效了，但是if (!flag) return不管用，依然回走下面方法，哪里写错了
