This is not related to your issue but you should set your UI resolution to 1080p 60hz as running it in 4K as you have it set now is problematic.
I also noticed this in your advancedsettings.xml
<cache>
<memorysize>0</memorysize>
<curlclienttimeout>45</curlclienttimeout>
</cache>
Setting memorysize to zero is problematic. If you want to return it to defaults replace that line with just…
<memorysize/>
and as for the timeout you put that in wrong. It won’t work inside cache tags and it should be…
<network>
<curlclienttimeout>45</curlclienttimeout>
</network>
I also spotted this error in the file…
<videoscanners>
<ignoreerrors>true</ignoreerrors>
</videoscanners>
should be a singular videoscanner such as
<videoscanner>
<ignoreerrors>true</ignoreerrors>
</videoscanner>
<nofliptimeout>0</nofliptimeout> is not supported in Kodi anymore
Still probably not related but…
MYSQL: Connected to version 5.5.62
Current versions of Kodi seem to be less compatible with MySQL versions older than 5.7 then it once was. Upgrading to a newer version if possible would be a good idea.
CServiceAddonManager: starting script.xbmc.unpausejumpback
I forget the details but there exists issues with this add-on.
I’m not sure what’s up with the errors in scanning and I got crossed eyed before finding any of them. If you fix the errors I outlined above in your advancedsettings.xml file the message should get suppressed like you wanting though.
