Just for anyone who sees this and doesn't know the solution, if your OS is installing a MTR version newer than 0.86 it will not work. I believe Almalinux (if I remember correctly) installs MTR 0.92 which won't work, I built a few versions and 0.86 was the most recent that works, there is some change in MTR 0.87 that is problematic, I looked at changelog and couldn't find why. Attached is a bin for 0.86, just replace /usr/sbin/mtr.

@Yakashimoto @themikeambrose we have made a complete new rewrite which works with latest MTR: https://github.com/hybula/lookingglass
