Lua error can't fix it

I have a bug that comes up randomly multiple times in dungeons, I can highlight buttons with my cursor but can’t click on them. It’s like I can click through them and turn screen instead of actually clicking on buttons. I can’t even accept a ress sometimes. This can last for a few minutes and disappear by itself but most of the time I have to open task manager while in dungeon and that way it disappears for a while but comes back again of course. I need to open task manager several times while in dungeon. It’s really frustrating as I’d like to do high keys of mythic + but it won’t be possible with this bug. I tried everything UI reset as showed on blizzard support page, deleting addons, updating addons, console cvar_default command, scan and repair, nothing works. I contacted support a week ago but didn’t got an answer since. I ran a command to show Lua error it seems the issue comes from the Interface/FrameXML folder.

Here are some pictures of the Lua error (I have addons in this pictures but it doesn’t make a difference): imgur…com/a/r7NFjbR

Here’s a video of the bug after I’ve done everything possible to fix it (deleted addons, ui reset, after cvar default command): imgur…com/a/vL0AKbk

I hope there’s a solution for this it’s really frustrating and I really hope i won’t have this issue in raids aswell as i’m starting progress next week with my guild.

I can’t post links so thats why I put multiple points instead of one. At least let me show others my problem blizzard as I’ve been trying to resolve the issue for a week now.

That kind of LUA error looks like it’s Addon related, and judging from the screenshots you definitely have some of those running.

Two things you could try:
Disabling all your Addons and turning them back on one at a time until you find out which one might be causing the error,
or
An interface reset.
A reset will get things back to defaults for you but it will clear the error.

If you do want to run Addons do try make sure that the Addons creator has made sure they are up to date with the latest version of the game or you may see more of those LUA errors.

Thats exactly what I did it didn’t work. Read all my post! Please don’t give me the same generic solution that I’ve tried at least 10 times and didn’t work. I know that on the imgur pictures I have addons but I’ve also sent you a video with everything on default and no addons DELETED addons. Including twitch app and everything that installs addons automaticaly. In case you don’t believe me and still think it’s due to addons I’ve sent you pictures that clearly shows there are no addons and even like that I still have the same issue. I’ll say it again I’ve tried every solution proposed everything! (cvar default command,etc). I renamed files as InterfaceOld, WTFOld, CacheOld. I even tried deleting them and login with no interface, wtf, cache files nothing works!
