Update on the glibc problem (only applies to linux users):

The root cause of the problem is that I upgraded my build system in the last year and now have a newer version of glibc. Anyone using a version of glibc older than 2.33 will have this problem. The problem seems to be with a new symbol "fstat" which was not even in the old binaries (according to objdump).

I think the solution is for me to downgrade my system to an earlier version. This will break other things for me, so I am hesitant to do this in the near term. Since this app is a beta version and most runtimes take over 2 hours on the UHD 620/630 cards and hang on lesser cards, it seems like this app will not get much use until the newer intel cards come out in 2022. Hopefully by then I can improve my build system, so we can stop having these compatibility issues.

I just added support for Intel GPUs. There are 2 versions - 64 bit linux and 64 bit windows, both require openCL 1.1 or higher.

Can it have anything to do with the fact that sytems that haven't contacted the server for a while cannot update at the moment?
