Can't decrypt messages encrypted with my public RSA4096 key - 2-byte hash error

[antonyb]

INCOMPATIBILITY / REPORTEDLY DEPRECATED KEY WITH HASH
Error: Error in openpgp.decryptKey. Error decrypting private key: Encrypted private key is authenticated using an insecure two-byte hash
It could relate to: openpgpjs/openpgpjs#1000. Even could relate to 5.0.0 version of openpgpjs (https://github.com/openpgpjs/openpgpjs/wiki/V5-Changelog/83d7b1a1b9098213d7a70ae8ec00fcb62f99d60e). I think the error appeared in some release during 2023: mailvelope/releases

I have created my public and private key in 2018 (relatively new) via GnuPG software AFAIR. After some time in 2023 Mailvelope started to fail decrypting messages bellow stating two-byte hash error (first I thought it's a wrong password, but different msg was shown, decryption works with GnuPG).
How can I find out via openpgpjs (GnuPG won't provide detail information as PGP old software on hash-bytes as illustrated in http://www.spywarewarrior.com/uiuc/ss/sec-key/sec-key.htm#pgp-cvt) detailed information on hashing, S2K and so on?

The future might bring another backwards compatibility issues: openpgpjs/openpgpjs#1672.
When it comes to ECC, what algorithm serves the best security and speed of calculation and durability in the future?
Where should I generate new key pairs, Mailvelope provides nearly no information on key details, I need information like pgpdump in Linux, but for Windows, this program used to provide very detailed information on keys.
