After update to CoreELEC 9.2.1 - the system stopped working

Hi,
After the latest update I’m not be able to start any addons previously installed.

Coreelec has became very slow and when I start a video addon it stuck on loading.

Here the kodi.log when I’ve tryed to start youtube.

CoreELEC:~ # 

My device is a TVBOX S905X with 1G of RAM. (It was born with Android but I’m booting CoreElec from SD card.
I know that 1 GB is low but before this update ithe system was working.

Can you give me any advice?

Thanks

Please try to put new posts into the correct category rather than General.

It looks to be an issue with your weather.gismeteo addon.

Try removing it, SSH to your device and execute the following.

rm -rf /storage/.kodi/addons/weather.gismeteo

If it helps I had issues with same addon . I now use yahoo weather.
Easy to change in settings.
