Studio stuck on DataModel Loading on "detailed" places

When trying to load any place that is decently sized (any above around 10k parts) it just keeps getting stuck on this DataModel Loading stage, some times it loads more stuff but still not 100% of the place, it does this and then one lucky time it works fine (1 out of 20 times).

My system specs:
CPU: AMD Ryzen 7 2700X Eight-Core Processor
RAM: 32GB
GPU: NVIDIA GeForce RTX 4060
I use cable Ethernet with good speed

Below is a screenshot of its worse state, not even the sky loads:

Another screenshot of the bug in another place:

The thing is, not even studio own UI loads properly, like this game settings menu:

Expected behavior

It should load the place correctly, with the sky and meshes and textures fully loaded and showing. Like the image below:

after enabling network logs here’s a picture when trying to load one of those places:


I tried everything, from restarting my PC, to deleting roblox completely and reinstalling it but nothing works

Do you have anything set in Studio Settings->Network->Incoming Replication Lag?
