調査の方向性
Start by reproducing the failure through Settings → export contacts to a .vcf file, including contact sources and saving the export. Then trace the contact-export flow and investigate why this device's contact data causes an IllegalArgumentException; the issue does not name source files or tests. Done means exporting all contacts creates a nonempty VCF that can be imported without errors.

Additional information
Additional information:
The bug exists a very long time (multiple years) unchanged. It was even there when the application was a part of Simple Mobile Tools and before Fossify was a thing. I hoped the next time I need to migrate to another device the problem would be fixed by someone else experiencing the same problem, but obviously it still hasn't. The last time I changed my phone to a newer model I needed to export just a few contacts one by one in order to circumvent the error from happening. I think the problem is caused by the number of contacts which I have (358 contacts as of today) and the amount of information inside some of them. I have noted a few infos like opening hours and similar things in some of them, in the "Notes" field.
