Unable to create a new custom field

[sstojanovic-godaddy]

I'm unable to create a custom field on IPAddress object. The process takes too long and eventually breaks. In UI it takes about 4-5 minutes and I get 502 or 504 error codes from the server. I tried increasing timeouts but the same issue happened. I tried adding a custom field through the console, and it was running for about 1h when the process got killed. It just said "Killed". I even tried to remove IPAddress from a custom field object types, or delete a custom field entirely but the same thing happens. I assume this is because I have a lot of IPAddress objects. How can I create/delete custom fields? I'm using Netbox v4.2.3.
