Realm.open() crashes compiler

[tsheninger-c4]

How frequently does the bug occur?

Always

Description

I use the line:
realm = try await Realm.open(configuration: config)
which should be calling
public static func open(configuration: Realm.Configuration = .defaultConfiguration, _isolation actor: isolated any Actor = #isolation, downloadBeforeOpen: OpenBehavior = .never) async throws -> Realm

When I build, the compiler always crashes:
Command SwiftCompile failed with a nonzero exit code

Here is more output from SwiftCompile:
Invalid bitcast %83 = bitcast i64 %77 to ptr, !dbg !254 Invalid bitcast %84 = bitcast i64 %78 to ptr, !dbg !254
