Installation Issues

So I was doing a new install of 4.2, and I followed the instructions in the doucmentation link:

https://docs.nopcommerce.com/en/installation-and-upgrading/installing-nopcommerce/installing-on-windows.html

After installing nopCommerce I get the following error:

System.InvalidOperationException: The property 'PermissionRecordId' on entity type 'PermissionRecordCustomerRoleMapping' is part of a key and so cannot be modified or marked as modified. To change the principal of an existing entity with an identifying foreign key first delete the dependent and invoke 'SaveChanges' then associate the dependent with the new principal.

Does anyone have an idea on how to solve this?

I've been installing a nopCommerce 4.30 on CanonicalUbuntu 20.04 by the steps described in installation guide. All was perfect, only one error (require to set log_bin_trust_function_creators = 1)  occur. After solving this error I tap the button "install" then "installing" message appears and after a while (1min) my system stopped to response any requests and rise "504 Gateway Time-out" in browser. It looks like the machine is missing until reboot - there are no any metrics indicated. After rebooting the system I could only saw an installation form again, but installation raise a error about "MySql functions already exists".

Trying to install on ubuntu-20.04-x86_64.
I followed instructions as stated here:
https://docs.nopcommerce.com/en/installation-and-upgrading/installing-nopcommerce/installing-on-linux.html
Then i grant mysql root access as per this article:

Then i load the page, enter details for install.... then after about a minute i get 504 Gateway Time-out.
Go back, restart installation, exactly the same thing.
