Harmony 21 Crashing on Start-up

Hello! I am a student, and I use Harmony very frequently. Recently, I noticed Harmony 20 was crashing for me, but I thought I just had corrupt files, so I downloaded Harmony 21. Now, whenever I try and start a new file, the program freezes up. My computer is more than capable of using Harmony, so I don’t know why I’m having this issue! My specs are Nvidia GeForce RTX 2060, Intel Core i7, plus a 500GB SSD. Are there any solutions for this?
