Hi,
I got very strange error of workflows our SharePoint.
We are using SharePoint 2019 on Premise and Windows Server 2019 Standard. After some yesterday windows updates, which weren't even connected to SP (screen below), workflows (specific 2013 Workflow) do not work and even didn't show up in SharePoint Designer. It's look like it wasn't configured, because I don't see even option do create 2013 Workflow.
I am wondering: should I reconfigure workflows hoping that it will reappear, or should i do something else? I don't want to lose them, because we were using them a lot.
EDIT: working solution in reply from @JulieWang-MSFT
Didn't work.
I had to delete "Workflow Service Application Proxy" from Web Applications to reregister it. But since it was registered maybe this is not place where it is a problem.
It's strange, because looking further into it from all information that I got from serwer it is working fine, but I can't do anything practically.
From central Administration:
From Management Shell:
But in SharePoint Designer i got:
And of course I don't have my site workflows that I created on website. It's just blank.
If there are no other options, maybe I should reinstall it and if needed restore its databases (WFManagementDB, WFInstanceManagementDB, WFResourceManagementDB)?
Please check if the workflow service connect to your web application via Central Administration>Application Management>Manage web applications> choose the web application and click Service Connections:
Oh, it's started working. Thank you.
In this popup window at start I had chosen group [custom] and there were no option checked.
Strange. So, since I had different than default group chosen this mean that if I click OK when I have chosen to edit e.g. [custom] this group will be used?
Maybe when I was searching options to resolve this problem I clicked wrongly and it was in fact ready to work after register (hint from @Emily Du-MSFT ) but missing this one option.

1.Install the SharePoint Designer 2013 Service Pack 1 (SP1).
2.Clear SharePoint Designer cache.
3.Register the web application to workflow service again.
Register-SPWorkflowService -SPSite 'https://webapp.domain.com/managedpath/sitecollection' -WorkflowHostUri 'http://workflowhost.domain.com:12991' –AllowOAuthHttp
4.Restart the server.
