iCloud云盘持续以3M/S左右的速度向C盘写入

iCloud云盘在Windows系统上持续以3M/S左右的速度向C盘写入，Logs文件夹内可见其创建的100M-2GB的日志文件

日志文件夹内日志大小多数在1-10KB，从4月25号开始生成大小不正常的日志文件，最大时有2GB，如下图：

日志文件内有较多的WARN和ERROR，如：

[18088 @ Tues May 02 2023 20:33:35.240] 20080 ERROR CKWD::PCSManager::RollMasterKeyForRecordPCS Couldn't roll master key for record PCS <PCSShareProtection@0000022C7078B380: [ MasterKey ID: f4ca2633e6f5951a956c5ce1c5322438b9a6c0ed6eee98e5ad8183fa44e349ba PCSKey: NO PCSPublic: YES validated: YES version2: NO light: NO readwrite: YES] >: Couldn't roll master key for record PCS: (1,5005)

并持续占用10%-20%的CPU，怀疑是BUG，资源管理器截图：

目前没有发现解决办法，已经禁止iCloud云盘自启动了。强制停止后再启动，问题依旧。
