Unable to download subtitles since 2023.06-1

I updated to 2023.06-1 this morning and found I am no longer able to download subtitles through subtitle addons. First I get an error “Error searching for subtitles” and then more specifically “Failed to download subtitle”. This happens with opensubtitles.com as well as the subscene subtitles addon.

The logs show the following exception:

OnDownloadComplete - Saving of subtitle /home/osmc/.kodi/userdata/addon_data/service.subtitles.opensubtitles-com/temp/326b0b01-6d8f-4d1c-b1fa-a6a3bc39b902.srt to special://temp/Wind.River.2017.1080p.BluRay.x265-RARBG.en.srt failed

I have tried resetting the vero to defaults, to no avail. Any help would be appreciated.
