In our SharePoint 2019 production environment, we are unable to install App and Remove App as getting error. We could see that Application Installation Service timer job is went to paused state. Checked in ULS logs , the error at the specific time stamp is "Completed processing of timer job [job-app-install-queue] with lock type [None] against target instance. Status result: [Paused]"

"Completed processing of timer job [UnifiedPolicyFileSyncUrgentJobDefinition] with lock type [ContentDatabase] against target instance Status result: [Paused]. Status ressage (if any): []."

Please help me to find the cause of this issue and how can we bring back the "Application Installation Service" timer job to success state and fix the issue.

Try to use the PowerShell command to restore the Default Farm-Scoped timer jobs:

$farm = Get-SPFarm

Restart the SharePoint Timer service via Run->services.msc.
