'C:\inetpub\ShadowCopyDirectory\585.\MyApp.API.exe'

Is that path correct? The . after 585 is suspicious.
Can you share more logs? https://learn.microsoft.com/aspnet/core/host-and-deploy/iis/logging-and-diagnostics?view=aspnetcore-8.0#enhanced-diagnostic-logs

Yea the path is correct (hide the actual app name) as I copy pasted this from event viewer.

I don't know when this error will come again so can't share with you logs now. Will keep an eye and update.
Thanks for the help.
