进入设置，个性化锁屏默认选项是空白的，切换到图片，幻灯片也不显示下拉选项，无任何变化。
你好
也许 设置 应用没有正确加载该页面的控件。尝试修复，必要时重置 设置 应用。
先关闭设置。
打开开始，输入Settings，右键点击设置结果，选择应用设置。在 **** 打开的设置应用页面，点击修复，等待修复完成。
再次打开设置，进入锁屏>个性化，切换到图片或幻灯片，看看照片选择器或文件夹选项是否出现。如果没有变化，回到同一个应用设置页面**，点击****重置**，然后重启电脑。
重启后，回到锁屏>个性化，再次尝试图片或幻灯片。你现在应该看到 ** “用浏览按钮选择照片**”作为图片，或添加文件夹“用于幻灯片”。
如果这还没解决，请告诉我你是否看到页面顶部显示“部分设置由你的组织管理”的提示，并从设置>系统>分享你的Windows版本，关于> Windows规格，这样我可以指导你下一步。
修复和重置都已经试过，没有效果，重启电脑依然无法选择任何图片
补充一下，背景图片设置完全正常

Hmm, since Repair of Settings did not help, the most likely cause is a lock-screen policy left behind in the registry.
Close Settings.
Open Start, type Windows Terminal, right click Windows Terminal, choose Run as administrator.
In the elevated window paste the lines below and press Enter. They back up the policy keys to your Desktop and then delete them. If a key does not exist the command will simply report that and continue.
reg export "HKLM\SOFTWARE\Policies\Microsoft\Windows\Personalization" "%USERPROFILE%\Desktop\LockScreen_Policies_HKLM.reg" /y
reg export "HKCU\SOFTWARE\Policies\Microsoft\Windows\Personalization" "%USERPROFILE%\Desktop\LockScreen_Policies_HKCU.reg" /y
reg delete "HKLM\SOFTWARE\Policies\Microsoft\Windows\Personalization" /f
reg delete "HKCU\SOFTWARE\Policies\Microsoft\Windows\Personalization" /f
Restart the PC.
After the restart go to Settings > Personalization > Lock screen, set Personalize your lock screen to Picture or Slideshow, and check that you now see Choose a photo with the Browse button for Picture, or Add a folder for Slideshow.
Tell me what you see after this. If the controls are still missing, I will move to the next step and reset the lock-screen component itself.
没有效果，执行后如下图
