An unexpected error occurred( file ", line, function ")
There has been serveral bug reports about this - the issue was introduced in the March 2025 update.
It has not been fixed yet, even in the May 2025 release.
The general recommendation is, if possible, downgrade to the Feb 2025 version.

This has not worked, weirdly, if i change the scale from the left hand side of the slicer, it works, but not from the left (Lower Bound)
Hello,
I'm experiencing the same issue. What's strange is that I tested opening the project on two other Dell laptops and the problem doesn't occur only on this somewhat old Intel desktop that I left at the company for BI project development.
I tried rolling back Power BI to the February version, but my project won't open in that version.
I hope Microsoft can fix this bug soon.
