Forge Becoming Unresponsive

Hi all!
I’m having major issues, using the Simple Worldbuilding System and about 12 mods including LiveKit.
Basically, both I and my players are having to reload after about an hour of play. Audio starts cutting out, the interface becomes unresponsive/laggy, I can’t upload/access any of my files, and I have to restart. When I reload the page, it takes forever and when it finally goes back it’s even more laggy than before.
Now, I see that it’s update time once again, and I fear that that will only exacerbate these issues.
Any guidance on the matter would be much appreciated.
