Indesign Not Loading Past Opening Window

[samarag74007589]

Since updating my Mac to macOS Big Sur 11.3.1, I have been unable to open and load Indesign. The program opens, put no windows appear (pic below) and any option to create new doc crashes. 

Any help or thoughts on what I can do to get it operating normally again?
