Text tool not working properly

[#1]

I have a Mac running Catalina. Photoshop is up to date. When I try to use text tool it just shows "Ipsum" in huge black letters (must be about 1000pt in size) even though I have tried to set it down to 6pt. Can't add new text at all. Sometimes I see "Rendering text". I have reconfigured tools. Any ideas, please?

Try resetting the tools and/or preferences.
To restore preferences quickly using a keyboard shortcut:

Press and hold Alt+Control+Shift (Windows) or Option+Command+Shift (Mac OS) as you start Photoshop. You are prompted to delete the current settings. The new preferences files are created the next time you start Photoshop.
Note: Using the keyboard shortcut, preference files for custom shortcuts, workspaces, and color settings will also be reset to default.

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Photoshop forum.
