Form is broken on single machine after moving to Win10

This is my first message here, so let me say hi
I have a file used by couple of people in my company. It contains a lot of vba code and few user forms. It's been working perfectly for years now on all machine. Recently 1 machine has been migrated to Windows 10, the excel major version hasn't changed though (16). For reason unknown, 1 of the forms lost almost all the controls on it and the user is getting "Compile error: Method or data member not found" at the line Me.cmbWeek.ListCount (as this control is not existent for the machine, although all other machines 'see' it perfectly well (also migrated to Windows 10 but flawless). You can find both form and its code behind here: github.com/robs23/ProductionSchedule/tree/master/Forms. The find the forms both on user's machine (broken) and on all other users' machines (proper). I was going to show both broken and working forms here but apparently I can't be trousted as a new user.
