Is there a program that closes an application and then reopens it after a set amount of time?

I need this program on windows because a certain software I use has a tendency cause issues when left on for too long, which restarting it completely fixes.

You can try Task Scheduler

Which program are you using? Do you have the latest version?

What operating system??

which operating system!..windows…

You could make a loop with a Windows batch file using ‘start’, ‘sleep’, and ‘taskkill’. If you’re not sure how to write a batch file, I can explain it in more detail.
