Additional information

Was running fine, but stopped working this morning, went to investigate and now I can't start it.

I am running, Ad Away, AdGuard, OSID Full and a custom URL for my block list. Would be happy to share any files you need to investigate.

[jakesteele]

I am only using the AdGuard DNS Blocklist the others are not enabled, and I deleted the /data/filters folder so its regenerated. Still the same issue.

[brunomiguel]

I have the same issue on Arch Linux with version 0.107.17

[PaperCutBad]

Same issue on Windows 10 with version 0.107.17.
