Sudden reboot and next error panic(cpu 0 caller 0xffffff7f972d53c5). What needs to be fixed in the system?

Question

macOS

Good day!
This problem occurs quite often and the laptop goes into a reboot against my will, its text is like this
. Could you please tell me what needs to be fixed in the system? The laptop was after repair, liquid was spilled on it and after that it stopped charging -> replaced the 2017 Mac thunderbolt ports on the board
error code:
