Can't resize my fonts in designs since update this is morning

Since updating this morning to 3.0.2.3912, I am unable to resize fonts in Affinity nor am I able to change the spacing between lines of text. Nothing happens. When I select my font, go to the Font size tool in the toolbar and attempt to resize as normal, absolutely nothing happens. I have restarted Affinity. but it did not work. I opened another project and tried to resizs a selected font there, and nothing.
