It is as issue with background plugin not bar-code scanning plugin as per the error trace mentioned by OP. 根据OP提到的错误跟踪，这是后台插件而不是条形码扫描插件的问题。
The crash issue is still open in background plugin as per the issue link with no resolution on this yet. 根据问题链接 ，崩溃问题仍在后台插件中打开，目前尚未解决。
Removing the background plugin for now should resolve the crash issue while bar-code scanning. 现在删除后台插件应该可以解决条形码扫描时的崩溃问题。
