@fearthebeardig I'm sorry I did not see a post by you and was addressing the error that abysswalkerpts reported.
I don't know your circumstances.
Yeah I know of the PowerShell method as my son had major problems trying to start the game on his system. Identical "twin" PCs, both brand new HDD (same brand and size) both with brand new installments of Win 10. Funny how something works on one system but not on an identical twin. Both systems bought brand new at the same time from the same vendor.
However it's my understanding that the PowerShell method is only to repair the Windows Store corrupted files. Be sure to reboot between Powershell and trying the game.
Below is the list of suggestions that the Sea of Thieves tech supp sent me. I hope it helps.
These are some troubleshooting tips below that may help you get into the game should you be one of the affected players.
Fix #1
Login to Windows 10 with a local Microsoft Account. This fixes majority of cases reported.
Fix #2
Open the Windows 10 Store, then in the top right corner click on the profile picture.
If you have multiple accounts signed in, sign out all of them but leave the email account linked to the game’s purchase signed in.
Next, in the Windows 10 Store download any free app at all.
Then try playing Sea of Thieves again through the Windows 10 Store “Library” page.
Fix #3
Go to the below link and save / run the tool. Follow the on screen instructions to troubleshoot / fix your issue.
Fix#4
Press Windows + R
Type Powershell and hit enter
Copy and paste the following into the powershell window and press enter
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
If your problem persists please create a support ticket for further assistance.
After trying their methods (except fix#2) and only having the game work once. I uninstalled and reinstalled it.
Thankfully it finally worked. Maybe doing the Powershell method before the reinstall is the answer?
