Version 2020 - CorelDRAW condition 5002--6951 Unexpected condition encountered.

I've seen other condition numbers online of older versions years ago but can't find this one anywhere.

Perhaps Thee Community can shed some light. Sometimes when I try to draw a select box around items only over the 8.5x11 page this error appears. Once a week this anomaly happens.

Cleared the temp files, rebooted & have been using since Corel 8.

Any insight into this one could possibly benefit others.

Thanks all.
