Spark does not open with folder redirection

I was wondering if I could get some help on this problem users are experiencing with Spark.

When the try and launch Spark, it never opens for them but it shows up under processes in task manager.

The users having this problem are all on folder redirection.

Spark version is 2.7.1.686

Windows 7 SP1 with all windows updates.

Any help is greatly appreciated.

Thank you.
