Audacity Not Responding=Windows10

Audacity newbie, here.

Quite frustrated. Completed an MP3/stereo file this morning. Exported and saved, no problem. Opened a new file, imported my audio, and was met with the message, “Audacity is not responding,” and then was given the option to either close the program or wait for the program to respond.

I have tried all manner of things… restarting laptop, shutting down, ect… at a loss… I just want to get some work done.

HELP!

Which version of Audacity (Look in “Help menu > About Audacity”)

I assume you mean that you opened a new Audacity project, then imported an audio file …

What sort of file? What format is it? How big is it?

Does Audacity import other files without freezing?
