System Error Critical on SIM slot swap

I’m trying to automate SIM swap changes via scheduler.

But I get an issue where on it runs successfully changes the SIM but it reboots with a system error even when its manually changed.

router rebooted because some critical program crashed.

RBLtAP-2HnD
Latest LTE modem firmware
7.18.12 rOS and Firmware.

Is this expected behavior? Pretty sure it didn’t use to on older routers of the same model.
