Cannot create project templates on my new pc (Studio 2021)

Question

I recently migrated Studio 2021 to my new pc, but when I try to create a new project template, I keep getting the error message &ldquo;Failed to load project template from C:\Users\(my name) etc. Could not find part of the path&rdquo;. 
 The odd thing is (and I suspect it is where the problem lies) that that path is a path on my old pc, not on my current one. Also, the error message appears before I have even got the chance to browse to a location - or do anything else, for that matter. The error message causes Studio to freeze and I have to shut Studio down using the task manager. 
 Can anyone help, please?

 Did you copy old templates from your previous computer perhaps? Or maybe the contents of your projects folder? 
 It might also help if you tell us the complete path so we have a clue where the problem comes from.

 ok - some instructions on how to clean up. Starting with a simple reset which often cures all ills. 
 You could use this app for the reset and this will also explain what you will lose by carrying out a reset before you do it: 
 appstore.sdl.com/.../ 
 But if you'd rather do this manually then rename this folder (just add _old to the end or something, it's not important what you rename it to) and restart Studio: 
 c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\Studio16 
 So the path would become this: 
 c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\Studio16_old 
 If you can't find this folder then you need to unhide your hidden files/folders:
