Hey,
it sounds like your db/ connectionstring needs to be configured properly.
What db are you using and how it the db server hosted?
How does the connection string look like and how is the db configured?
Please share as mucch information as you can - without sensitive information.
Kind regards Jack

i have another question , how to enable Hard Delete globally including implemented modules like (Saas, Identity ,etc..)

Happy to hear that,
You should be able to disable SoftDeletion globally following this here: https://docs.abp.io/en/abp/latest/Data-Filtering#abpdatafilteroptions

As what we understand, on record deletion, it started showing the deleted record after applying this configuration whereas it should be deleted physically (hard delete).
We applied this configuration in Application project....Is this the right project?

Application layer is okay, better put it in domain layer to spread it accordingly.
To your concern: Docs indicate only the "read-changes".
I've taken a look into the code on github. To me it seems like you disable soft deletion completely by adding the code above.
