What is this error? (Render frame was disposed before WebFrameMain could be accessed)

I'm having a lot of crashes recently, this can be the error?

Your system is extremely thin for what you are doing. The moment OBS is opened, there's less than 4GB of RAM remaining. There's no dedicated GPU, just an iGPU.

Issues:
SE
Too many Browser Sources
Rendering lag/GPU overload
Audio is lagging
Using the multi-output with no dedicated GPU

I would work on streamlining your Scene Collection/load reduction.
