Hey mageena,

Please remember to perform a search in our documentation for your error message before posting a new thread.

I’ve discovered a few threads where users had the same error and were able to resolve it.

Have a look and give those suggestions a try:

Have a great day

Somewhere in your project you’re making a call to a path that is invalid:

LongPackageNameToFilename failed to
convert ‘None’. Path does not map to
any roots.

I’d recommend starting with deleting your project’s Saved and Intermediate folders (make a copy of the project first with these folders in case you need to access backups stored there).

Also, try deleting the asset that caused the crash from your project’s Content folder to see if you are able to open the project without it. If you are, then you can assume the issue lies somewhere within that asset.

Those are a couple of debugging suggestions that you can start with.
