Problems in UART communication between ESP32 and STM32 - stm32

Question

I have a problem with the UART communication between an ESP32 and a STM32. Everything is working fine until I hardreset the ESP32 then I see a frame error on RX and in TX a shift in the response.
response. As soon as I hardreset the STM32 then everything works again and I see the same output as input. Can someone
help me?
