Assert failure(PID 2116 [0x00000844], Thread: 2156 [0x086c]): extraParamArgLocation == INT_MAX
    File: D:\a\_work\1\s\src\coreclr\interpreter\compiler.cpp:5641
    Image: C:\h\w\B5F40A08\p\corerun.exe

Reproduces consistently under DOTNET_InterpMode=3 when running the async tests.

Looks caused by #129442, cc @VSadov. It looks like the VM is returning CORINFO_VIRTUALCALL_LDVIRTFTN but also that the call has a generic type argument, which is an unexpected combination for the interpreter.
