Alright, let me walk you through what happened when I bumped into that annoying Honkai Star Rail system error 5151 the other day. It wasn’t fun, but hey, we got through it.
So, I was all set to jump back onto the Astral Express, you know, do my dailies, maybe push the story a bit. Fired up the launcher, hit the launch button, and instead of the familiar loading screen, bam! This little window pops up: “System Error. Code: 5151”. Just like that. No explanation, nothing. Game wouldn’t start.
First thing I did? The usual stuff. Closed the error message, closed the launcher completely. Waited a bit, tried launching again. Same error. Okay, maybe it’s just a glitch. Rebooted my whole computer. Always the first real step, right? Let everything start fresh. Waited for everything to load back up, tried launching Star Rail again… still error 5151. Great.
At this point, I figured it wasn’t just a simple hiccup. Checked my internet connection – everything else was working fine, browsing websites, other apps connecting okay. So, probably not my internet’s fault.
Digging a Little Deeper
My next thought was maybe some game files got messed up somehow. Updates happen, things get corrupted sometimes. So, I opened the Honkai Star Rail launcher again. Instead of hitting launch, I looked for the settings or options menu. Found the “Repair Game Files” or “Verify File Integrity” option, something like that. Clicked on it and let it do its thing. It took a little while, scanned all the installed files.
- Opened the launcher.
- Found the game settings menu.
- Clicked the option to verify/repair files.
- Waited for the scan to complete.
It finished, didn’t report any errors found, which was weird. I thought for sure that would be it. Tried launching the game one more time, feeling hopeful. Nope. Still error 5151. Ugh.
Okay, what else could it be? Sometimes security software gets a bit too aggressive. I checked my antivirus and firewall settings. Looked through the logs to see if anything related to Honkai Star Rail or its launcher was being blocked. Didn’t see anything obvious, but just to be safe, I temporarily added the game’s executable file and the launcher to the exception list, telling my security software to leave them alone.
Tried launching again. Still no luck. Error 5151 was really starting to get on my nerves now.
The Fix That Finally Worked (For Me)
I was running out of simple ideas. I remembered sometimes weird background apps can interfere with games. So, I started closing down unnecessary programs running in the background. Stuff like extra browser windows, chat apps I wasn’t using, anything that wasn’t essential.
Then, I had another thought. Graphics drivers. They can cause all sorts of strange issues if they’re outdated or have a glitch. Went to my graphics card manufacturer’s software panel (NVIDIA/AMD) and checked for updates. There was a new driver available. Downloaded it, installed it. This required another computer restart.
After the restart, with the new graphics driver installed and most background apps still closed, I held my breath and clicked the Star Rail launcher one more time. Hit “Launch”.
Success! The game started loading up normally. No error 5151. I finally got past the launcher and into the game login screen. Played for a bit just to make sure everything was stable, and it was.
So, for me, it seems like updating the graphics driver was the key step this time, maybe combined with closing some background stuff. It’s hard to say for sure which one did it, or if it was both. But since then, I haven’t seen that specific error code again. Hopefully, if you’re hitting the same wall, maybe going through these steps – verifying files, checking security software, and especially updating graphics drivers – might help you out too. Good luck!
