why trial version watermark appear in unity personal version?

when building windows programs with unity, trial version appears in the lower right corner of the program interface, which has never been seen before. The same problem happens in other unity versions.

might still a valid solution:

I don’t know why this happens, so I decide to use cracked version. Good job Unity team.

I just returned my Unity personal License and get it again (in simple words I refreshed my license list) and restarted my hub and project, and got it solved!
I’m facing this issue in Pakistan, Unity Hub Version : 3.5.2 and Unity: 2021.3.15f1
