I seem not to be able to get the new version 19.9.6.0 BETA to work.
When attempting to start TH it will throw me a Windows pop-up saying:
"The program can't start because <garbled message> is missing from your computer. Try reinstalling the program to fix this problem.
FYI - Until now I was able to run all versions meaning that my system meets the prerequisites (in case someone wonders)
I am reverting back using version 19.8.26.3 STABLE since it is still working.
I am not using 19.8.29.0 BETA due to lagging as reported by other users.
