CAN Transceiver TJA1043T communication interrupted

The characteristics of CAN1 communication interruption are as follows: Under the monitoring of the upper computer monitoring interface, after power-on, if no instruction is sent, the state of CAN is always normal.It starts with instructions, works for a few times, and then after a few times, communication breaks down.

 

I observed the waveforms of pins VCC, EN, WAKE, ERR_N and STB_N before and after interrupt,they are all normal.

The exceptions are TX and RX. RX garbled code, TX not returned after communication interruption
