Running server from different folder raises Internal Server Error.

I use Windows 11 with custom python path. So I have to run the server from the other directory than the project one.

I have just two folder here:

exllamav2/system #python folder
exllamav2/exui #ui folder

Run log:

C:\Programs\exllamav2>.\system\python.exe exui/server.py
 -- User dir: ~/exui
 -- Starting server on localhost port 5000
 -- Opening UI in default web browser
ERROR:ExUI:Exception on / [GET]

    raise TemplateNotFound(template)
jinja2.exceptions.TemplateNotFound: index.html

I fix the problem manually adding:

abspath = os.path.abspath(__file__)
dname = os.path.dirname(abspath)
os.chdir(dname)

at the start of server.py for now, so it forces to change the root directory.

The problem is caused by templates directory link, so a general solution would be nice.
