I'm having this issue occasionally after the update as well.
Sometimes it seems like the car is just "stuck" as I cannot shift into drive or reverse, use turn signals, etc... It will also sometimes think that my front door is open when it's not. It generally fixes itself after 15-20 seconds so it hasn't been awful, but definitely annoying.
It also tends to make really loud sharp static burst sounds from the speakers when this happens. This also goes away after about 10 seconds, but it is unaffected by the volume setting. I'm not sure if this is related to carplay or something.
I've tried the Air logo reset 3 or 4 times but this issue still crops up from time to time. I'll probably need to call the Lucid service center to see if they have any fix for this.
