The packet number in the trace log looks strange:
49796 -> 49798 -> 49800 -> 49802 -> 49804.......................... -> 49797 -> 49799 ........ -> 49805 -> 40807

And Connection->Stats.Recv.ReorderedPackets is increasing rapidly(about 2000 - 15000 per second), but Connection->Stats.Recv.Droped and duped is zero.

Does it mean these packets are out of order?

This is caused buy a bugy switch.
If someone encounters this problem, try decrease MTU in QUIC settings, If issue disappeared, check the 'REAL MTU' of swtich/router with IT guys or device vendor.

Thanks everyone in discord.
Especially Nick Banks and Anthony Rossi!
