Multicam became inaccessible halfway through the project

I've been editing this zoom call through multicam set up and everything was working fine until halfway through the projejct the multicam set up decided to stop appearing. I can still go in, right-click mouse on the sequence and change the angle on the options menu, however the multicam select screen does not show up anymore, It just shows the angle selected twice instead. (Source monitor is how it should look for me)
