I would suggest looking at GSE - Support and where to get help
It generally states if it’s important post it on GitHub. Why? because that the home for GSE.
Your vague thing of “it’s broken fix it” gives me a total of zero insight into your problem.
As a guess I’m assuming that you havnt been paying attention to the further changes Blizzard has made to click which came into effect last night. You might want to look at the troubleshooting guide for that issue here: GSE - Support and where to get help
If that’s not it, you are going to have to use GitHub and raise a support request and supply some very specific information.
The current working versions of GSE that are compatible with this WoW version are: 3.1.18, 3.1.19, 3.1.19-PatronBuild and 33.1.20-PatronBuild
3.1.18 and 3.1.19-PatronBuild need Load out of date addons. This has been fixed in 3.1.19 and 3.1.20-PatronBuild respectively. Outside of this these versions are the same as their predecessors.
