Sorry for your troubles, but first of all you decided to use beta versions, whose character is, that they might not be fully tested.
You should only do beta testing, if you are willing to provide constructive feedback and accept, that there might also be things that won't work.
I suggest that you untick the beta program option in the LRTimelapse settings. Then close LRTimelapse and download the latest official (non beta) version from the download page:
https://LRTimelapse.com/download
Always make sure Lightroom is closed before installing!!
Now you should be up and running.
This being said: all the things you mentioned are not things you usually need to worry about at all. Also nothing changed regarding the Filters and LR Addons in the latest betas. All Lightroom Addons will get installed automatically to the right place when you run the LRTimelapse installer. The only thing you need to take care of, is closing Lightroom before installing LRTimelapse!
It's absolute counter-productive to try to download any add-ons at all from dubious websites and trying to install them manually. Don't do that. This is not necessary.
If you encounter any problems, this is the place to ask.
I hope I could help!
PS: in another post of yours you wrote that your are still using the (nearly 10 year old) Lightroom 6. This might still work with LRTimelapse in Masks 1.0 mode, but could also be the reason for your troubles. That old Lightroom is not officially supported since quite some time, as you can also find in the EULA that you agreed to when buying/downloading LRTimelapse.

You should definitely consider upgrading to Lightroom Classic.
