I am trying to add web server on windows server 2019 but it is throwing an error

Hi @MoreManishDISWGSCSGSSGDNDOTALMTEST-1391
Error 0x80073701 is ERROR_SXS_ASSEMBLY_MISSING, it means there are some system files are missing, which caused the update installation failure.
Resolution:
Run the checksur.exe (System Update Readiness Tool) tool.
Run System File Checker. From the command line run the command sfc /scannow
Examine the language packs installed on the system. Uninstall the unnecessary language packs.
Review the cbs logs and uninstall the patches which were missing assemblies and reboot the server.
Reinstall Service Pack 1.
