This sounds like a second issue unrelated to the one with scraping. When you see that dialog don’t remove the file. When using fstab to manualy create a mount point sometimes it can be slow making the connection or it can become interupted after some time. You can try (if not already done) setting wait for network in the My OSMC add-on or add a wait time in Kodi’s power settings. Even still it can happen (under what circumstances I don’t know) and if that is the case then you would probably have better luck changing the manual mounts over to using autofs. You can find a guide for that [here]
Your logs for Kodi didn’t upload with the rest. It might be a bit more clear what is going on if you included those.
Someone else would need to chime in about the font issue as that is not something I’m familiar with. On a completely unrelated topic you should switch your UI over to 1080p as running in 4k like you are is prone to causing issues.
