LE 11.0.3 pre-dates the RPi5 release, so no 
We are still thinking about if or how we include RPi5 support in LE 11 (eg 11.0.4).
Background info: we've been testing with LE12, which runs entirely 64bit code and can take advantage of several nice optimizations (eg accelerated deinterlace) which are only available on 64bit.
LE11 on RPi is entirely 32bit userspace code though. Adding 64bit support to it would open a can of worms (lots of the addons would need updates etc) so likely I'll have a look at doing a 32bit LE11 RPi5 build as this should be easier to achieve (fingers crossed).
so long,
