Ok so Ive had constant freezes with 2021.12.1 so have reverted back to previous version 2021-09-0-3703 and have been using it without issue, same hardware, I would like to help find the problem but without some sort of debug mode or error files its pretty difficult. For your reference here is some details of my setup and solution.
1.Windows 11
2.postgresql 12
Large solution built completely for NGClient, lots of inherited forms and methods, no 'special webcomponents' just what ever is available from Package Manager.
