Pressed Spacebar-No space delivered & grey box appears?

[Yossarian-C22]

Guys, I have a problem.

In writing apps, around 70-90% of the time.
If I press the spacebar, I get no space between words, and a grey box appears in a 'sensible zone', sometimes larger than the example below.

macOS 12.3
Mac Mini M1
Ulysses & all writing apps.

I can’t type reams, I have ALS. Thanks in advance.

Duplicate - happened while trying Accessibility

I believe it may have to do with Accessibility - pressing space is the command for Full Keyboard access. In my case, it puts a box around things.

Thanks guys,
Very-interesting I’m typing on the Accessibility-Keyboard and it’s happening here now. I-only get the spaces by using the text predictions which come with a free space tacked on.
