### 'Error: Could not fork child process' while opening Sage

Hello,

SageMath 8.8 worked just fine but for a few days now whenever I open the console I get the following error:

Error: Could not fork child process: Resource temporarily unavailable (-1).
DLL rebasing may be required; see 'rebaseall / rebase --help'.


I reinstalled a few times with no luck. My Windows 10 has been updated recently so perhaps it is something in the latest update that interferes? Appreciate if anyone got around this.
