не хватает места на мониторе

the document cannot be opened because there is not enough space to pin it on this monitor
what is it and how to fix it

Hi @asus pa 249q For this monitor error, did you try resetting your Preferences? That usually clears things up. Instructions are here: https://helpx.adobe.com/photoshop/using/preferences.html#Manually

If that doesn't work, in Photoshop under Help > System Info, copy and paste the text into a new reply here, and we'll take a look.

you do not need to do anything that you advise. The reason for this problem is that the mode was set to open in tabs, and in the working window there was an unpinned property panel

Hi, does pinnning the Properties panel fix the issue? I do not understand the scope of your post.

надо прижать панель к левому или правому краю рабочего пространства,там где
панель инструментов или панели расширений

you need to press the panel to the left or right edge of photoshop  workspace with toolbar or extension bars.
