Heya, sorry to hear that is happening and that's incredibly odd since that event shouldn't have changed anything with how the game operates. It isn't connected in a way that could possibly have an effect on performance or stability, but stranger things have happened. Have you tried any troubleshooting, like just restarting the device or doing the repair option on the main login screen?
Also, to answer your other question we have seen that request for hybrid or thermal scopes plenty, especially since Season 12: Going Dark (2020), but we don't have any news to share on that front. Similarly, no major changes to Gunsmith are expected in this next release, but we know that is something people care about and are looking to share info about it whenever we can.
