Hopefully you will get a reply from Frederik (program author) in due course but there's not a lot to go on here as to what the problem might be. Did UF give you the opportunity to send a bug report?
A little tip: If you ever see this bug report dialog but the program is not responding just remember that the report data is also automatically copied to the clipboard, so you can usually paste that into an email to info@ultrafractal.com
I am no expert, just a user like yourself, but I have one small suggestion for something you could try. It may not be the culprit but it did cause a problem for a small number of people at one time...
Go to View menu > Preferences > Fractal tab
Find option for "Enable OpenGL acceleration" and de-select / uncheck it.
Re-start UF and see if this helps.
