Family Sharing Max
Increase the Family Sharing Max from 5 https://steamcommunity.com/sharedfiles/filedetails/?id=873543244#:~:text=below%2E-,Family%20Sharing%20%E2%80%94%20Library%20for%20friend%20%28Regionally%20limited%29
library_sharing_account_max = "5"
Note:
The standard limit for the number of accounts you can authorize for Steam Library Sharing is five (5) accounts.
This limit applies to the original, legacy Family Sharing feature. In late 2024, Steam introduced the new "Steam Families" feature, which replaces the legacy sharing and has a higher limit of six (6) family members. The user query about a library_sharing_account_max console command refers to an unofficial, unsupported method to bypass this limit, which may violate the Steam Subscriber Agreement and is not officially recommended
Note:
