rsl file not found

Hello, I am running a simulation under premium 2022 random vibration.
This simulation has worked perfectly until today.
After 1 minute of simulation I receive the error message saying:

" The .rsl file was not found "

I have the continuous calculation undone. At the end of the calculation, I have no results.
Do you have a solution to this problem?

Thank you in advance for your support

Hello;

Usually, this problem occurs when working on a server or on an external disk.
Try duplicating your elements to be evaluated (parts/assemblies) on a local disk of your PC, then restart your simulation...

Kind regards.

Hello, the part/assembly data is local.
On the other hand, the license is floating on the network.

I changed my live solver sparse ald feeplus. In config I don't have this message anymore
It remains a mystery
