Pterodactyl std:system_error
std:system_error means that your server is using a software called pterodactyl. This software kills VS for making too many threads, with the only fix being changing a setting that customers usually don't have access to. You can try and ask customers support to see if they will change it, but with large server host companies (bisect, Aternos, etc) they almost certainly won’t since it’s an important part of them regulating how much resources each server uses.
Here is the GitHub bug that mentions how to fix it:

Its worth noting that Minecraft itself, along with other mods, also use multiple threads. VS just uses the most, and so is usually the one to push it over the limit.
