Serena is crashing wsl at 75%. WSL just closed terminal window

[visioncourse]

When running the index, it gets to 75% then just crashes the WSL terminal window. I have the latest WSL. Anything I can do to debug? im guessing it's finding a file it doesn't like and then crashes. Docker is not running when this happens, nor any other terminal window, only trying to reindex. When I got back into WSL and tried to index again. Get a message that there is an error message:
ERROR 2025-08-23 10:08:53,656 solidlsp:load_cache:1665 - Failed to load document symbols cache from /user/project/abc/.serena/cache/typescript/document_symbols_cache_v23-06-25.pkl: Ran out of input. Possible cause: the cache file is corrupted. Check for any errors related to saving the cache in the logs

yes, pls do. And check the serena project index-file command - with that you should be able to identify the culprit file
