Rhino doesnt start on windows - need help please

my hardware asus pro art laptop with rtx a3000 ada

latest windows update 2xH something

latest grafik card driver

few days ago i needed to do some work via rhino - the welcome window just disapears after trying to load plug ins. i was trying to follow which plugins these are, still didnt work

made a fresh installation, for removing rhino i used revo uninstaller pro… no additional plug ins, out of the box - rhino keeps crashing on welcome screen presumably loading plug ins…

does anybody have suggestions, workarounds, expirience with same/similar situation? i wouldnt know where to start like if there is any way to look into logs without having the possibility to actually start rhino…

thanks in advacne!! best regards, konstantin

starting in safe mode i get a message PlugInLaden couldnt be resolved during loading a plug in(kann nicht geladen werden, während ein Plug in geladen wird)),

Hi Kostyantyn -
Have you tried repairing the Rhino installation from the Windows Control Panel?
-wim

just did that - unfortunatly it didnt help:-( was hoping it could be an easy one…

Any errors?

When opening in safe mode it will ask you to load the default plug-ins, say yes then run SystemInfo and post the results. Thanks

the first message, when i start rhino in safe mode, i did post above already. then i get asked if i would want to load the Calc.rhp

SafeMode disables your graphics and non-essential plugins for troubleshooting.

Do you have any errors in your Windows Reliability Monitor?
