Second time App error
I encounter a very strange issue with two apps: Pulse Secure and TexStudio.
The first time when I downloaded and install these two apps, everything works fine. But after I restart my laptop, both these apps encounter some problems and can't function well. The Pulse Secure can't pop up the window for username and password. The TexStudio can't work with the error 'Error: Could not start the command: pdflatex -synctex=1 -interaction=nonstopmode '.
I am using a Late 2013 Macbook Pro with Catalina 10.15.2. Can someone help me with these issues?
MacBook Pro 13″, macOS 10.15
