While this issue has been confirmed in CorelDRAW 2025 with the June 2025 Update applied (version 26.1), and a fix is in the works for a next update, there is a workaround:
In the Edit Text dialog, select "Options" and uncheck the "Show Font" option. For now, please uncheck that "Show Font" option to work with the "Edit Text" dialog in CorelDRAW 2025 June release.
I am also seeing this issue in CorelDraw 2025 but not in 2024.
