Just downloaded UE5.1 and I have it together with UE5.0.3.

But when trying to start 5.1 version I get error code LS-0013.

Tried verifying, change to admin (then it doesn’t launch at all), tried to update Windows/GPU drivers, removing webcache, turning off Antivirus/firewall, disable background apps… but no luck.

Any advice?

Hey @RBTheO,
I know it’s probably what you were trying to avoid, but it seems at this point you might just need to re-install 5.1.
I’ve also seen a couple of issues where the GPU driver actually needed to be downgraded technically, as the most recent driver was helping cause issues.
I hope this can help, I wish I had more advice to give!

Preview 2 came out today, unfortunately it did not solve my problem.

@RBTheO
Are you downloading it through the launcher? Also, out of curiosity, what are your computer specs? I’ve seen an issue like this on Reddit where the person’s HDD had suffered some wear and it was causing the read to not function the best.
You may have more luck with this kind of error code through this link:

I hope this can help,
