'File monitoring failed' error message while running complex brms model

I have been running a multivariate model in brms. It has been running for over 72 hours. After two days the following error message was displayed in the console

Warning message: File monitoring failed for project at "G:/filepath" Error 2 (The system cannot find the file specified) Features disabled: R source file indexing, Connect, Diagnostics

The model is still running but I can’t tell if I should wait for it to finish or if the error message means something has gone terribly wrong and I should stop it.

Does anyone know what this means?
