Why does Matlab 2015b crash when I try to save a .m file?

3 views (last 30 days)
Matlab consistently crashes every time I try to save a file no matter the size of it. I can still reopen the files that were opened beforehand and save files that already exist but making new ones is impossible. I've already tried uninstalling the program altogether and reinstalling but the issue hasn't changed. I would appreciate some help with this issue.

Hi Robert,
for this kind of problem I would suggest to support MathWorks Technical support (see here).

Hi Robert,
First, please confirm if you are using a Dell Machine. If yes, please disable the Dell Backup utility on your machine for this folder and try reproducing the issue again. There are few known issues when MATLAB is trying to save a file to directory which is being monitored by the Backup utility.
If it does not resolve the issue, please send us the crash logs. For instructions on how to gather crash logs, please refer to the link below:
Thank you, Adithya Addanki
