I have done some testing since the last post.
my guide data is this

Guide_Data ={ "channelname": "Test Channel 1", 
"channelnumber": 14, 
"channellogo": "", 
"isfavorite": "False", 
"guidedata": [{
    "url": "", 
    "starttime": 1583807560, 
    "endtime": 0, 
    "runtime": 3600, 
    "label": "Test show 1", 
    "label2": "HD", 
    "art": {
        "thumb": ""}, 
    "streamdetails": {
        "video": ""}
    }]
}

and the call to uepg is,
xbmc.executebuiltin("RunScript(script.module.uepg,json=%s&refresh_path=%s&refresh_interval=%s)"%(urllib.quote(json.dumps(list(Guide_Data))),(sys.argv[0]+"?mode=1"),(urllib.quote("7200"))))

I pasted the log as you requested, i hope i did it right, lol

Thanks again,

Log is missing debugging from uEPG, you can enable it from within uEPG's settings....

The only visible issue below.

Change : (urllib.quote("7200"))))
To "7200"  

Ive checked and debugging from uEPG was enabled.
The error i saw in the log was,

2020-03-10 13:53:27.564 T:72444   DEBUG: script.module.uepg-1.0.6-notificationDialog: uEPG Error, Contact Lunatixz for support
2020-03-10 13:53:27.564 T:72444   DEBUG: script.module.uepg-1.0.6-__main__, params = {}

i have changed my call to ,
xbmc.executebuiltin("RunScript(script.module.uepg,json=%s&refresh_path=%s&refresh_interval=%s)"%(urllib.quote(json.dumps(list(Guide_Data))),(sys.argv[0]+"?mode=1"),("7200")))

and here is a new log with debugging still enabled.

Thanks for your time 

With the limited info provided, I'm not sure what the issue is; however, it's not a uEPG issue.... rather how it's being implemented.  You can post a GitHub link to your project, when I'm free I can take a look.
