The RaspberryPi 4 uses an ARM Chip. Trying to install amd64 packages does sound quite weird to me.

The Minecraft deb package only ships with a x86-64 executable. There is a Minecraft Pi Edition at https://www.minecraft.net/en-us/edition/pi/ but it seems to be quite different from the actual java edition.

There is a Tutorial at https://www.raspberrypi.org/forums/viewtopic.php?t=137279 for example. Maybe it still works, but I haven't tried it out.

The Minecraft.deb has the default-jre dependency. On Ubuntu 20.04 this is openjdk-11-jre.

There are two (admittedly hacky) solutions I came up with to fix this:

• Edit the Minecraft.deb file by unpacking the 'control' file and replacing the "default-jre" dependency by "openjdk-8-jre". Then put the .deb package back together.

• Download the Minecraft.tar.gz archive from the website (Other distributions button). Unpack it into your desired location (default for the deb is /opt/minecraft-launcher). Create a symlink in /usr/bin and/or a .desktop file in /usr/share/applications. Make sure just openjdk-8-jre is installed.

There are probably better solutions out there, but those are the ones I came up with. The update-alternatives command could probably work too and would be way simpler, but I didn't try yet.

Yeah a BIOS-Update fixed it for me. Really seems to be related with the Ryzen 3rd Gen hwrng bug.

Same here with Ryzen 5 3600 and 1660Ti. Maybe has something to do with Ryzen 3rd Gen hwrng problems?
