Arrgh! "Sorry, something is wrong with your data."

Question

TL;DR: Why did iMazing cause me to get this alert? (Context: I'm security cautious. I get annoyed when, for example, I'm forced to install the root certificate "Kaspersky Web Anti-Virus Certification Authority" in order to install the latest Kaspersky anti-malware software. (Previously this was optional). But this post is about DigiDNA's iMazing.) I was surprised by this macOS pop-up this morning."iMazing wants to export key" "from your keychain".I'm hesitant to give ANYTHING access to a private key on my system, and the key in my keychain is a private key, as is the key name "iMazing: (3AC1<...>)"I wonder what this is. Instead of messaging support, I'm posting in a public place, as others may well have the same question and google for answers. Relevant?: I recently used a private Personal Code Signing Cert with Org name to sign a 'thin' Beta copy of Thunderbird. (Created with ditto -v --hfsCompression --arch arm64 /Volumes/Thunderbird/Thunderbird.app /Applications/Thunderbird BETA V.99.ARM64.app and signed with codesign -s /Applications/Thunderbird BETA V.99.ARM64.app )that has the OrgName too! I just composed a LONG question and tried to post it and got this! > Sorry, something is wrong with your data.I loaded https://www.macobserver.com/community/ios-questions/ to no avail. But then magically / by manually saving my complaining post, 0 Revisions turned into 3 Revisions, and (the body of) my post was recoverable. YMMV.
