Strings that are too long in one line are not rendered

OS: Windows 10 Pro 20H2
Ai Version: 25.2.1

This problem is probably caused by documents that are larger than about 2000px on a side.
If the text has no line breaks and exceeds a certain font size, the text will not be displayed at all.
Image output is also not possible.
It is also common for this problem to occur at the same time as Adobe Fonts license errors and save errors.
In most cases, the number of characters that stop the string from rendering is more than 1000, but it may have something to do with the font size.
I apologize for all the inaccurate information, but I hope this helps you solve the problem.
