Windows 6.2.1 x86_64 toolchain is resulting in exit code -1073741819

While debugging a vscode-swift issue https://github.com/swiftlang/vscode-swift/issues/1937 I came to realize something is different with 6.2.1 toolchain on Windows. So we call `swift --version` and various other SwiftPM commands on extension activation to setup the development environment. With 6.2.1 we get the right STDOUT but exit code -1073741819 which I think indicates STATUS_ACCESS_VIOLATION. ``` PS > swift --version Swift version 6.2.1 (swift-6.2.1-RELEASE) Target: x86_64-unknown-windows-msvc Build config: +assertions PS > $LASTEXITCODE -1073741819 ``` Now I'm reproducing using the x86_64 toolchain on ARM64 Windows because for the longest time ARM64 toolchain did not work on Windows. I tried installing the ARM64 6.2.1 toolchain on Windows and the extension activates fine so I only reproduce with x86_64 toolchain on an ARM64 Windows but that worked as recently as 6.2.0. I downgraded to 6.2.0 and 6.1.3 with no issues, so think legit issue with the x86_64 toolchain for 6.2.1
