Hi @soundblaster,
Could you please quickly try this: run services.msc on your primary machine, then find spacedeskService and try if you can easily stop-start it.
For further analysis, please go to spacedesk Driver Console -> Diagnostics, click Save All Information button.
PS: Saving all information will take a few seconds, then please send us the whole folder which contains all the diagnostic logs collected.
Please right-click the folder -> Send to -> Compressed (zipped) folder, then attach the *.zip file in your next reply.
