Crashes my steam when big games are running

[StarSap-sik]

I am not using a steam beta client, nor does my partner. Whenever I try to stream some games, the program completely shuts off my steam connection. It works fine for small games, like Deltarune, and also for streaming OBS studio, but whenever I launch any game that doesn't contain pixel graphics it turns off my steam connection.

Any way to fix this? Is this even fixable? Please, I need help with this
