Yes, I think you'll have a problem building the package.
Reading the comments there seem to be other suggestions, like changing the PKGBUILD before building in order to specify the python-jsonschema version, so you might try that as well.
There are also other comments mentioning other dependencies (e.g. python-sentry_sdk, python-urllib3), not clear to me (I have only quickly read the comments in the 1st page...) although they seem slightly newer in the last update than the comments. Just try...
I tinkered a tiny a bit with no real solution. Unfortunately I just started a python project that is going to take a month or two, so not only do I not have the time to deep dive right now, but I can't risk messing up my python packages. For now I will just have to run GNS3 on my Pop OS install. I will circle back around to the issue asap, because this is the only program I can't get to work on Garuda. If/when I figure it out, I will post the solution. I really appreciate the advice. I'm sure it's the path to my solution.
