It also could be something wrong with my AppImage setup. Could you please run the following commands and post their output?
nm -D /lib64/libelf.so.1 | grep ZSTD_compressStream
and
find / -type f -name libzstd.so.1 -exec sh -c "echo {}; nm -D {} | grep ZSTD_compressStream" \;
Also could you please name your Linux distribution and its version? I can just set it up in Virtualbox and try and fix things from there.
