Profile installing deadlock

[Felix14-v2]

I confirm the following:

• [X] I checked the existing issues for duplicate problems
• [X] I have tried resolving the issue using the support portal
• [X] I have ensured my Modrinth App installation is up to date

Info

Modrinth App 0.8.5 Windows 11

Description

Modrinth App can't finish duplicating an instance if the original instance is running, so you get a broken instance:

To reproduce

1. Create an instance
2. Launch the game
3. Open a world
4. Try to duplicate the instance
5. You got a broken instance because of inability to clone the session.lock file

Expected behavior

Ignore the session.lock file and other files that you can't copy
