VSC loses opened files

[Qualdan]

Issue Type: Bug

Using with Unity. If I open VSC with "Open C# project" -command it reopens all previously opened files. But if I open VSC by activating a single script (from inside Unity), all previously opened files are not opened and every single one needs to be opened manually again.

VS Code version: Code 1.49.1 (58bb7b2, 2020-09-16T23:27:51.792Z)
OS version: Windows_NT x64 10.0.18363
