yes as I have said earlier, switching to legacy does not resolves the issue.
I haven’t tried the patch yet,

No it is not theme specific,
As I posted in my query, in basic troubleshooting I changed the theme, and issue remained.
It was persisting with default theme and our custom themes as well. The issue also persisted when we installed the demo wordpress website from the scratch.
