Line function no longer working in 2D

I have 2D and was working with 2022 version. Last week, the "Line" command stopped functioning, or would worked one time, and then stopped functioning. Either way, I couldn't draw a line by way of a dimension. On occasion it will work then abruptly end. I have not changed any formatting, new computers, or graphics card, etc.. I updated to 2023, still have the issue. I deactivated the program from my laptop, and activated it on my desktop: same issue. I am still working on Windows 10, so not sure if that is the issue. I use it on a daily basis, and it had been working fine until last week.
