Premiere freezes during simple operations

The problem appeared in the public version 26.2.0 after the last update: each timeline zoom (and sometimes selecting several clips on the timeline) causes the program to freeze for several minutes. More than that, during this freeze, the whole system stacks up, and we have to wait until Premiere starts working again. 

I saw this problem during the last months in Premiere Pro Beta, but now it’s in a public Premiere as well. What could be done to solve it?
