Hi guys,
got some good news for you even if it took some time: I just released 2.15 that should fix this issue!
Some words about the cause:
I accidentially used some language features (like the String.isBlank() method) only available from java 11 on. I didn't notice it because i'm on linux where package managers always deliver new java versions automatically while you seem to use windows with java 8 installed and with no auto-update. I reverted that changes so limbomedia works again from java 8 on.
To prevent such issues in future releases i decided to bundle the appropriate java version into the windows release, so there's no more need to install and update java manually what makes running limbomedia on windows even easier.
Sorry for all that trouble and waiting, hope to hear from you if things are running smooth now,
Thomas
