When trying to open certain c or h files in my project, Segger Embedded Studio (latest version) gives a very longwinded uncopyable dialog message that there was an error decoding [path to file] - check that the correct encoding has been selected.
The encoding is the same for all files (and some open without the error). IN spite of the message, the project still builds, deploys and runs and these files are essential. One can still open the file. This problem does not occur with the same project files (cloned from git) in an earlier version of Segger Embedded Studio running on my laptop.
