This is a bump of two previous reports on the same bug:
- 'isBlocked' error makes playerlist inaccessible on Roblox, requiring you to rejoin
- No error management for "isBlocked" causes Playerlist to become unusable
Both reports have been closed without solving the issue.
There continues to be an issue on Roblox, although rare, where you can experience the playerlist going not closing/opening due to a corescript error. You have no way to reopen the playerlist unless you actually re-open Roblox, which disrupts our experiences.
The screenshot below shows the stack. The error happened yesterday: 15th of July 2026.
Expected behavior
I would expect the playerlist to remain usable at all times for when it is needed
