There is very little actionable information to work with.

What has the User ( you ) done to try and fix this issue ?

Generally, closing the Application completely

Then, hold the SHIFT key and try to launch the application from the Applications folder

This is called a Safe Lauch of only the application

Does this work ?

If not >>

Restart in Safe Mode.

This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts.

The boot up will be slow and can take some time - Normal.

Safe Mode will also eliminate Third Party Software, extensions and drivers from loading.

It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance

Does the issue present in this mode ?

Sometimes a Safe Boot followed by a Normal Boot will just put things right.
