Hi @nholzbach,

Sorry to hear that your colleague is experiencing issues.

There seems to be an issue with your LCI database which makes your database unable to be processed. Going by the error it looks to me like the amount field of one of your exchanges has an unexpected value. I would try to inspect your database visually by exporting it as an excel if that is still possible, or otherwise through Brightway directly.

For now this doesn't seem to be an issue with the Activity Browser in particular though.

Kind regards,

Marin
