In the logs you attached (thanks for that by the way!) I found this line:

logger=plugin.manager t=2022-06-02T10:53:45.11+0200 lvl=eror msg="Could not start plugin" pluginId=frser-sqlite-datasource err="fork/exec /var/lib/grafana/plugins/frser-sqlite-datasource/gpx_sqlite-datasource_linux_amd64: no such file or directory"

For some reason Grafana does not see the file. Maybe it is a permission thing? I see the root user owns the files. Maybe grafana needs to be the file and folder owner?

I have two ideas you could try:

1. (remove the current plugin folder and) reinstall the plugin via the grafana-cli but without sudo (so it is not the root user who executes this command and creates the plugin)
2. Change the owner of the plugin folder to the grafana user (probably grafana but maybe check what users you have): sudo chown -R grafana /var/lib/grafana/plugins

@fr-ser this is most likely a NixOS specific issue, in which it is trying to find the dynamic loader in a path that does not exist in NixOS; happens when trying to execute a binary in NixOS that was created in another distribution like Ubuntu. As such, I'm closing this issue.
