Why does this error after loading a map?

Everything loads like it should but... after loads at 50% its someways errors. :/??? Umm I have tryed a lot of different codes for it but nothing worked yet.

Output = {
10:19:06.511 - ServerScriptService.Map:103: attempt to call a nil value
10:19:06.512 - Stack Begin
10:19:06.513 - Script 'ServerScriptService.Map', Line 103 - global LoadMap
10:19:06.514 - Script 'ServerScriptService.Map', Line 138
10:19:06.514 - Stack End
}

(Its a HUGE map) I believe the error is when it trying to find the Gui again and cant because of the Map Generaton lag.
