Question about key verification with GnuPG 2.2.25

[gnupgpacker]

Hello,
my attempt to verify all keys with GnuPG-2.2.25 shows this response:

$ gpg --refresh-keys
gpg: 59 Schlüssel werden per hkps://hkps.pool.sks-keyservers.net aktualisiert
gpg: ...
gpg: signature packet: hashed data too long
gpg: read_block: read error: Ungültiges Paket
gpg: Anzahl insgesamt bearbeiteter Schlüssel: 27
gpg:                             unverändert: 27

In gpg.conf option
charset utf-8
is set only.
GnuPG-2.2.25 has been installed as part of Gpg4win-3.1.14.

How to further explore the shown errors:
gpg: signature packet: hashed data too long
gpg: read_block: read error: Ungültiges Paket

How to identify / correct affected keys?

Thanks and best regards,
Chris
