"Current operation is not supported while updating value!" Error anyone who can help me make sense of this?

Not sure why, but, just had this same issue, cross referencing our mod lists, we have bluehead, give-ui, pack n strap, in common, the first mod I tried getting rid of, give-ui seem to have worked for me, but I have no clue as to why. Your issue might be different as-well seeing as I couldn't get in at all.

i have same problem, but with lots of WTT weapon mods, gun mods, some gear mods and SVM as the only game tweaker and Blue head AIO as merchant. the install is fresh from today, clean and it was first raid attempt on a 3.9.X version. the error is happening on all maps and i can't get past loading.

this may be a mod related issue in my opinion. i'll put my list via a screenshot Here

I'm getting the "Current operation is not supported while updating value!" Error when normally the "Deploying In:" screen would show up, I'm not quite sure what's causing it.

I know my modlist is a bit of a mess, if anyone has any sage advice I'll gladly take it.

If any more information is necessary I'll gladly provide it.

Thanks in advance for taking the time to read my issue.

Edit: Forgot to mention when I restart the server I can play 1 raid and get the error on the next raid, I can basically play 1 raid per server restart.
