assert failed: twai_handle_tx_buffer_frame twai.c:183 (p_twai_obj->tx_msg_count >= 0) if CONFIG_TWAI_ERRATA_FIX_TX_INTR_LOST=y (IDFGH-8204)
See original GitHub issueThe TWAI interface has a bug that causes the chip to reboot if you short / have interference the CANBUS pins. There is a proposed solution in the IDF github.
For that I need to adjust the IDF TWAI component:
# TWAI configuration
#
CONFIG_TWAI_ERRATA_FIX_TX_INTR_LOST=y
Does anyone know how I could implement it in the Arduino/Platformio enviroment?

Not a platformio issue anyways. You can start here https://community.platformio.org/t/framework-espidf-arduino/14949 There is already a open issue in IDF, search the error or wait until it is fixed or use the old working core.
Please note espressif32 3v5 does not use TWAI but CAN. espressif32 4.4 uses TWAI (with the bug)
