就像標題所說，一切都按預期工作，直到我從 9.2.15 升級到 9.3.15 它是基於作曲家的安裝。
當我嘗試存取其中一個路徑時，第一個路徑給了我這個
網站遇到意外錯誤。請稍後重試。
SymfonyComponentRoutingExceptionRouteNotFoundException：路由「user.admin_permissions.module」不存在。在 DrupalCoreRoutingRouteProvider->getRouteByName() 中（core/lib/Drupal/Core/Routing/RouteProvider.php 第 206 行）。
人員選項給了我這個：
The website encountered an unexpected error. Please try again later.
SymfonyComponentRoutingExceptionRouteNotFoundException: Route "user.role.settings" does not exist. in DrupalCoreRoutingRouteProvider->getRouteByName() (line 206 of core/lib/Drupal/Core/Routing/RouteProvider.php).
作曲家沒有錯誤，任何日誌中都沒有錯誤，儘管這出現在我的 access.log 中

Composer 在更新時沒有顯示錯誤，我還透過 drush 更新了資料庫。任何日誌中也沒有錯誤。
不是 100% 確定是什麼修復了它，但我從備份中恢復並從 8.9.18 重新啟動並清理了我的模組資料夾。有些模組是透過drupal UI 安裝的，僅在我的模組資料夾中，而不是在module/contrib 中，因此我卸載了這些模組並將它們從模組資料夾中刪除，然後透過Composer 重新安裝並啟用它們。之後，我清理了快取並執行了 drush updb，然後像之前一樣繼續升級到 9。然後就成功了。
