I feel your anger about this unlucky incident, i myself had a similar issue the made me lost some imaging days and it is due to my stupidity of the moment. The last weeks i was feeling a jiggly motion at the focuser area of my rc scope and i couldn't locate it, maybe it was the focuser drawtube? But during the last two weeks when i tested a fresh install of indi at my pi the collimation of my scope was completely bonkers, i packed my equipment went inside home and did a collimation (this happened twice at my limited days off from work), the last time i had the same issue after recollimating my scope i was near the point of selling all of my equipment and stopping this hobby. But then as i was placing my rc scope on the ground i noticed that the whole collimation plate of the primary mirror was loose, turns out i kept forgetting locking the collimation plate of the scope so naturally my collimation was going to get problematic after each movement of the scope.

Sorry for hijacking your post for my story, but i had to vent some steam.

Also for a new guide camera i would suggest the SX Lodestar camera or the SX2 Lodestar, i have successfully located a guide star with my Lodestar camera through an OAG at my RC scope (1624mm) at a white zone.
