Are you using the snap version?

[Marathon2112]

No, I'm using the jabref-latest package on the AUR (uses https://builds.jabref.org/master/JabRef-portable_linux.tar.gz as a source).

[LyzardKing]

@Marathon2112 Could you try the portable install? to see if the problem is with the aur package or the official build as well?
You can use the one you link to in the comment

Not a problem for me with today's master beta (deb).

[Marathon2112]

@LyzardKing Works with the portable install. Must be a problem with the AUR package. Closing, thanks.

For reference, solved by making jexec executable:

chmod 755 ./lib/runtime/lib/jexec

[rs028]

Just for future reference, I had to change the permissions to 755 of the following files:

./lib/jabrefHost.py
./lib/runtime/bin/*
./lib/runtime/lib/jexec
./lib/runtime/lib/jspawnhelper
