Less than an minute problem on MacBook Pro 5,5 HELPPPPP

Hello I’m trying to install Monterey on my MacBook Pro 5,5 from 2009 I Upgraded the Mac with an 500gb ssd (SanDisk SSD PLUS)And 8gb RAM im stuck on this screen for 2 hours i know that it’s old hardware but does it take this long? Should i just wait? I installed Monterey with open Core Legacy Patcher on a 16gb SanDisk USB Ultra. Please help me if some of you guys know how to fix this problem😊.And sorry for my bad English I’m from Austria✌️.
