Backport of #123931 to release/10.0
/cc @hoyosjs @tommcdon
Customer Impact
When loading and unloading an Assembly multiple times in new AssemblyLoadContexts Visual Studio will abruptly end debugging before program completion with the following error:
Originally reported via Visual Studio feedback item Fatal error encountered when debugging .net 10 app using collectible assemblies in VS2026, then moved to GH issue #123930.
Regression
Regression from .NET 9, introduced in .NET 10 on #117224 and was a missed case when attempting to address the issue in #118414.
Testing
Validated with customer's reproducible test case on #123930
Risk
Low. The debugger module caches uses the module as the hash key rather than the assembly. This was a missed case when fixing #118414 where we were still incorrectly using the assembly as the lookup key.
