Where can I find Components_Pages_pagename_razor.g.cs? [duplicate]

So since yesterday I have been getting this error:Severity Code Description Project Path File Line Suppression StateError CS0103 The name '__builder' does not exist in the current context BoltonBicycleKitchen C:\Users\A S U S\BoltonBicycleKitchen\Microsoft.CodeAnalysis.Razor.Compiler.SourceGenerators\Microsoft.NET.Sdk.Razor.SourceGenerators.RazorSourceGenerator C:\Users\A S U S\BoltonBicycleKitchen\Microsoft.CodeAnalysis.Razor.Compiler.SourceGenerators\Microsoft.NET.Sdk.Razor.SourceGenerators.RazorSourceGenerator\Components_Pages_RegisterCyclist_razor.g.cs 321 Active

I cannot find 'builder' or Components_Pages_RegisterCyclist_razor.g.cs when i search them up or follow that path on the error.

I tried deleting my RegisterCyclist.razor file and recreating it. The error still exists.
