Hi,

 

Had this error with 3.4 (see attached screenshot)

installed 3.5 (pgadmin4-3.5-x86.exe) -> same

De-installed and restarted -> worked

Closed program and started again -> same screen ever since (see attached)

(FYI: when you click on the only available menu ("Object") nothing happes)

 

Thanks for any help, Moritz
