macbook pro – Dual screen disconnect on macOS Big Sur with high temperature

As mentionned on this previous post i have frequently disconnections with my second screen and my MacBook Pro (13-inch, M1, 2020) chip Apple M1 and macOS Big Sur 11.4

I note that it happends during periods of high outdoor temperatures (35° C, 95° F) because when i place an electric fan in my desk near my MacBook it works fine.

My thunderbolt port is 48-49° C (120° F) and connected with hub.

Have any of you already had this problem ?
