Sorry you are going through this too. I just received mine back today after 2 mos. They repl transmission , torque converter, hybrid module and transmission cooler due to metal shavings.

Did they give you a loaner?
My LC with just over 1000 miles just had a very similar issue last night. All kinds of warning notices and a hybrid system malfunction notice. All the notices cleared but these two (pics of notices attached below) stayed. For a moment felt like transmission was slipping and lost hybrid power. Pulled over and restarted it. After that It drove fine but the notice is there. I scheduled a service appointment for this coming Monday.

I'm surprised by how many people have had this issue come up. No probs here . . . so far. I feel for you guys/gals, though, and wonder when (or if) it'll happen to my LC.
Question: Just as many of us do a preemptive oil change as a guard against machining debris in the engine oil, would any of you recommend a preemptive oil change for the transmission fluid? Would that have even been of help? It seems a small price to pay for peace of mind.
OTOH, if a simple oil change were an effective fix, wouldn't Toyota have offered a free one already? I have to think Toyota knows of this issue and is on top of it.

Took it in for service, the service advisor said that there was a fault code for a transmission solenoid. They are keeping it for another day to drive it more. If it doesn’t happen again and keeps driving without anymore code faults they said they will release it back to me. I’m hoping it was just a glitch, glad to get it back. I’m not too worried about it, if something happens again they will figure it out.
Update Edit
Driving fine for two days now no issues.

Update,
After 7 weeks the LC is ready to pickup. New transmission , torque converter, hybrid module and transmission. I have notified Toyota I want a full refund. I'll wait till 2025 or 2026 and try again. What a shame.
Same : ( Only had I have 10,000 miles. Vehicle went in end of November and might get it back beginning of Feb with a whole new transmission and hybrid module.
Wow..this happened at 10k miles. I was hoping to be safe going past 5k. It seemed like this happened at less than 4k miles for every incident so far.

I just had the Hybrid System Malfunction/Drive-Start Control System error again today for the third time since getting the LC in August. Two of the times it’s happened in pick up line at my kid’s school and the other was in slow moving traffic. The other two times I took it in and they couldn’t replicate it but did open a case with Toyota. I guess I need to take it back in again but the dealer is 50 minutes away.
