Hi Tracy,

Thanks for posting on Microsoft Community. We regret the inconvenience caused and will assist you in resolving the issue.

Node.dll is a type of DLL file associated with Windows 10 operating system. DLL (Dynamic link library) files such as Node.dll are small programs, similar to EXE (executable) files, which allow multiple software programs to share the same functionality.

Method 1: Run SFC scan by following steps from the link below and check if the issue is resolved.

SFC scan is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. If a Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected. For example, some Windows functions may not work, or Windows may crash.
