Hi - I would need more information surrounding the part of the code which reports the actual error. It should be displayed just before the notification to report the issue.
You can either post that here or in Discord for faster help and I can help you out.
Its possible you are launching the application from commandline without changing into the directory first.
One thing you can try is installing with the itch.io launcher rather than downloading the Zip file and running it manually.
Any warnings can be safely ignored - the tensorboard warnings are known and shouldn’t affect the performance of the application.
