Acrobat crashes when filenames exceed 256 characters

I had the issue of Adobe constantly crashing only after opening files a second time following a reinstall. None of the troubleshooting methods worked. I finally contacted support and discovered that the files opened fine when saved to the downloads folder or the desktop. The customer service person then suggested that the problem was due to my exceeding a file location character limit of 256 characters. It seemed logical since the files opened fine when saved to the desktop or the downloads folder. However, I manually counted the characters leading to where my files were stored, and it came nowhere close to 256.

Now I'm wondering if it has to do with the fact that these files are stored on my iCloud drive. Perhaps that adds significantly to the character count in some way. In any case, it is frustrating to change my organizing system to one that requires that I save PDFs to my desktop to open them. I'm anticipating an administrative nightmare as a result. While this technically works, and the customer service person considered the problem resolved, there's got to be a better way than this.
