Hi! To be honest I haven't encountered that issue either. Camera position should be bound to a certain range from the dice. As a short term solution try to double-click the middle mouse button (or CTRL + left mouse button) - on the background, not on the dice - this should reset the camera to a default position.
If you have time, you can try to record this behavior (using OBS, for example) and send it to me alongside with a log file you'll find at C:\Users\{username}\AppData\LocalLow\DiceMaker\DiceMaker\Player.log. Just try to reproduce the issue, stop recording, close the app, and send me the video and the latest log file at dicemaker.app@gmail.com.
