Looks like a permissions issue and remember in linux plug-ins have to be executable. Do not like those warnings about GLib-WARNING / theme engine . Did you copy your Windows Gimp 2.10 profile over wholesale?
Does the Windows linux setup come with a file browser or just a terminal?
If you have a browser it could be possible to check and adjust permissions from that, otherwise a terminal and the chmod command
This is very-very not good practice but might prove things one way or another. In a terminal
Makes everything available to all users and everything executable. Only the plugins need to be executable but maybe get something working first.
chmod values, useful calculator here: https://chmod-calculator.com/ and the man page https://linux.die.net/man/1/chmod (in case man chmod in a terminal does not work)
