Regular hard crashes since updating to 6.4.1: "FATAL ERROR: v8::ToLocalChecked Empty MaybeLocal"

Description:

We updated RC from 6.2.0 to 6.4.1 last week and since then we have regular but seemingly random crashes.
This is the error message we receive from the rocketchat docker container:

Start with the reported Node/V8 stack traces, especially the llhttp and @kaciras/deasync binding frames, and compare the 6.2.0 and 6.4.1 server environments. Use the Docker setup with Node v14.21.3 and MongoDB 5.0.21 to seek a reproducible crash; done means identifying the regression and verifying a fix.
