Turns out our issues are not related.
My instance the issue is that somehow FRR 7.5 doesn't respect my prefix-list filter for inbound. I had it set to
10 permit ::/0
20 deny allto only receive default route from upstream. Since upgrading this is ignored.
show ipv6 route bgpShows the entire routing table being accepted which obviously causes issues with a lab VM that has 1GB of RAM.
OP runs on powerful bare metal so the VMware thing was a red herring.
My instance that is not effected is only receiving default route from the neighbor so the issue did not show.

It turns out the isssue was not related to yours. My issue was prefix lists were not migrated correctly and did not work. FRR 7.5 uses a different syntax to 7.3 and when I upgrade pfSense from 2.4.5-p1 to 2.5.0 the preflix list filters are not applied because of this. It meant the instance was accepting more routes than what can fit in its RAM and things started falling over.
Your instance is bare metal with plenty of RAM so it's a different cause.

Every time I have to use service frr stop command,
Webgui can only be used after FRR is stopped -
