These are add-on errors. Specifically:
When you do send log fragments (if you must do so), please only include the fragment that results in errors (typically a fragment that starts with "error" followed by timestamp and traceback). While the info log does not contain input and output data, it still contains enough information to figure out specs of your system and user path.
A tip for folks parsing NVDA logs: the log analyzed is one of those that include tracebacks from add-ons. You can determine involvement of add-ons in error messages if parts of the traceback refer to what appears to be NVDA user configuration folder path, and that probability increases if the error traceback does end with an error coming from an add-on. I state the last sentence like this (increase in probability) because:
I think the log fragment posted indicates issues beyond NV Access's control; no, actually these are issues beyond NVDA developers' control as add-ons are involved in the log fragment, more so for this fragment. I suggest contacting authors of affected add-ons (for Sound Splitter, I have no plans to resolve this at this time as I'm no longer maintaining it).
