I have seen this error before on the forum, see: https://forum.mendix.com/link/questions/88560
Thanks for your reply. I am however experiencing the same problems. "Clean Project Deployment" Directory is not active and I can't find any Mendix folder in Local/Temp. I have deleted the content of Local/Mendix but that did not work.
I have a fresh install on Mendix. It works fine on my dekstop computer but not on my laptop.
Works again for me after deleting C:\Users\[username]\AppData\Local\Temp\Mendix
Note that AppData\Local is a hidden folder, so you need to enable seeing hidden files and folders in windows explorer.
