Error loading blcok – The response is not in a JSON response

Hello,

After updating to 8.1 I have a problem with the Gutenberg blocks in the layouts in the woodmart theme. All other blocks work normally without the error, but xtemos block has error:
Error loading blcok – The response is not in a JSON response
I tested adding an xtemos block in a standard post/page there is no problem, so the problem is only in woodmart layouts.
When opening some woodmart layout all hosting limits are at 100% (Physical Memory Usage, I/O Usage, SPEED Usage)
I wrote to the hosting company, they raised my limits, but still have this error.
Before the update to 8.1 this problem was not there.
I have no other plugins installed on the site, pure wordpress + woodmart + woo

Thanks!
