Try disabling all the plugins and see if the error is still there and if it's gone then enable them one by one till you find out which one or ones could be causing it.

i get the same error when i try to disable/enable a plugin, they do disable/enable though, i read somewhere it has to do with php 7.4 but when i try to go back to 7,3 xf stops working completly

Make sure you have the same extensions loaded for php 7.4 and 7.3 and then try doing it. I suspect if the site stops loading completely that a needed php extension is off. You can look at your server error logs when the site won't load on 7.3 to get a better idea of what extension is causing the site not to load.

You should contact your host then on that and make them fix the issue on the server. Otherwise, contact your panel support as this is something that they should help you with.
