When I try to open Excel, Word or PowerPoint files either from my OneDrive for Business or from one of my Teams, about 50% of the time, the office program never opens, it just get "stuck" like on the attached picture with a weird filename in the bottom. It is the same whether it is Excel, Word or PowerPoint.
I then have to "kill" the program and try to open the file again - this time I'm prompted to open in safe-mode due to a serious error.
Like I said, this happens about 50% of the times I want to open a file with the installed Office program.
I have a Office 365 Enterprise E3 licence and my installed Office is Microsoft Office Professional Plus 2016
