On the Raspberry Pi2 multiple patches conflict with the Leap 15.4 base system
and thus cannot be installed. Two specific examples are
openSUSE-SLE-15.4-2022-3022-1.noarch which conflicts with python3-cryptography
and openSUSE-SLE-15.4-2022-2102-1.noarch which conflicts with VIM.

I initially had run into a larger set of conflicting patches but suspected that
this might be caused by me having messed up something in my system going from
15.2 to 15.3 a while ago, and now to 15.4. However, I have now freshly set up
my Raspberry Pi2 with the JeOS image at
https://download.opensuse.org/ports/armv7hl/distribution/leap/15.4/appliances/openSUSE-Leap-15.4-ARM-JeOS-raspberrypi2.armv7l.raw.xz
and still run into the issue for the above-mentioned two packages. My
assumption is that other conflicts only got "resolved" because the re-install
reduced the amount of installed packages and the conflicting packages are no
longer installed.

Running zypper patch on my system ends with the following:

My list of repositories is the following. As you can see, except for my
personal repository with monitoring stuff, this is the standard repository
list:

Repository priorities are without effect. All enabled repositories share the
same priority.

With the limited digging I was able to do with my understanding of how openSUSE
for ARM is built, it seems that there is some inconsistency in the
python3-cryptography package version between "regular" Leap 15.4 and that for
ARM. As far as I can see it got upgraded in SLE15-SP4-Update, but this update
never made it to ARM, and I suspect a similar issue exists for vim.
