Today I upgraded from Linux Mint 19.2 to 19.3 (Tricia) and ran into the same issue. The PC suspends correctly, on resume I see the Mint logo, then after some seconds the machine reboots. There's nothing obvious in the logs between suspend and the reboot. I don't have an option in UEFI to disable TPM. Motherboard is an MSI MAG Z390 TOMAHAWK. Reverting to kernel 4.15.0-91 solves the issue. I'm happy to supply further details if helpful.
